Write Linear Equations & Understanding Slopes

The perpendicular slope for a given slope is the negative reciprocal of that slope. In this case, the given slope is -2/3. To find the perpendicular slope, we take the negative reciprocal of -2/3, which is 3/2. Therefore, the correct answer is 3/2.

The line x = -2 is a vertical line because it is parallel to the y-axis. In a Cartesian coordinate system, a vertical line has a constant x-coordinate and can intersect the y-axis at any point. Since x = -2 is a constant value for all y-values, it represents a vertical line.

The line x = -2 has an undefined slope because a vertical line does not have a change in y-coordinate for any change in x-coordinate. The slope is typically defined as the change in y divided by the change in x, but since there is no change in x for this line, the slope cannot be calculated. Therefore, the slope is undefined.

The equation of the line is in the form y = mx + b, where m is the slope and b is the y-intercept. Since the point (-1,0) lies on the line, we can substitute the x and y coordinates into the equation to solve for b. Plugging in x = -1 and y = 0, we get 0 = -2(-1) + b. Simplifying this equation, we get 0 = 2 + b. To isolate b, we subtract 2 from both sides, giving us b = -2. Therefore, the value of b is -2.

The given equation is in the form y = mx + b, where m represents the slope. In this case, we can rearrange the equation to y = (2/3)x + 1/9. Since the coefficient of x is positive (2/3), the slope is positive. Therefore, the correct answer is positive slope.

The equation of a line perpendicular to 3x - 5y = -1 can be found by rearranging the equation into slope-intercept form (y = mx + b), where m is the slope. The slope of the given line is (3/5). The slope of a line perpendicular to this line will be the negative reciprocal of (3/5), which is (-5/3). Using the point-slope form of a line (y - y1 = m(x - x1)), we can substitute the values of the point (3, -4) and the slope (-5/3) to find the equation of the line. Simplifying the equation will give us the standard form: 5x + 3y = 3. Therefore, the correct answer is 5x + 3y = 3.

The slope of a line perpendicular to another line is the negative reciprocal of the slope of the original line. Since the original line has a slope of 0 (because it is a vertical line), the slope of the line perpendicular to it would be the negative reciprocal of 0, which is also 0.

The equation is in slope-intercept form, which is y = mx + b, where m is the slope and b is the y-intercept. In this case, the slope is -3/4 and the point (4, -6) lies on the line. We can use the point-slope formula to find the equation: y - y1 = m(x - x1). Substituting the values, we get y - (-6) = (-3/4)(x - 4), which simplifies to y + 6 = (-3/4)x + 3. Rearranging the equation, we get y = (-3/4)x - 3, which matches the given answer.

The equation in slope-intercept form is y = mx + b, where m is the slope and b is the y-intercept. In this case, the slope is 1/20. To find the y-intercept, we can substitute the coordinates of the given point (-5, -3/4) into the equation and solve for b. By substituting the values, we get -3/4 = (1/20)(-5) + b. Simplifying this equation, we find that b = -1/2. Therefore, the equation in slope-intercept form for the line that passes through the point (-5, -3/4) with a slope of 1/20 is y = 1/20x - 1/2.

The equation of a line can be written in slope-intercept form as y = mx + b, where m represents the slope and b represents the y-intercept. In this case, the given line is parallel to y = -1/2x + 4, which means it has the same slope of -1/2. Since the line passes through the point (-4, -4), we can substitute these values into the equation and solve for the y-intercept. Plugging in the values, we get -4 = -1/2(-4) + b. Simplifying this equation, we find that b = -6. Therefore, the equation of the line is y = -1/2x - 6.
