(1, 3)-put first equation in slope-int form. x + y = 4 (subtract x from both sides) -x -x y = -x + 4. now, graph the y-int at (0, 4) and graph a few points above it by going up 1 and left 1....Read More

(-1, 4)-step 1: solve the first equation for y because it is easier to solve -3x + y = 7 (add 3x to both sides) y = 3x + 7 step 2: plug in 3x + 7 for y in second equation 5x + 2y = 3 5x +...Read More

(2, -3)-step 1: solve first equation for y (less messy) x + 2y = -4 (subtract x from both sides) 2y = -x - 4 (divide both sides by 2) y = -1/2x - 2 step 2: plug -1/2x - 2 for y in second...Read More

(8, -3)-step 1: solve first equation for y b/c it the easiest one x - y = 11 (subtract x from both sides) -y = -x + 11 (divide both sides by -1) y = x - 11 step 2: plug in (x - 11) for y in...Read More

(8, 1.75)-step 1: solve first equation for y less messy x + 4y = -1 (subtract x from both sides) 4y = -x - 1 (divide both sides by 8) y = -1/4x - 1/4 (leave them as fractions easier to deal...Read More
