The notion of line or straight line is to represent straight objects in geometry. Lines are an idealization of such objects, often described in terms of two points. Take this quiz to test your knowledge and clear your concepts about straight lines. Read the questions carefully and answer.

Y = 5x - 2
Y = -2x + 5
Y = 5x + 2
5x - 2y = 3
Y = 2/3 x - 6
Y = 2/3 x - 9
Y = 2/3 x - 3
Y = 2/3 x + 3
The slope
The Y-intercept
The X-intercept
The Z-intercept
Half of the initial value
Rise over run
Run over rise
X over Y
Y-intercept times X-intercept divided by pie
The opposite of the X-intercept
Y=-2x+18
Y=-(2/3)x+18
Y=-(2/3)x+6
Y=2x+6
Y=(2/3)x+18
Graph the slope, graph the y-intercept, then connect them.
Solve for y, plot the slope, plot the y-intercept.
Solve for y by isolating it, identify slope and y-int, plot the y-int, use the slope to plot another point then draw line through the points.
Put equation in standard form, find two points, draw a line through them.
