Question

Find the unknown coordinate so the line through the
points has the given slope

Answer 1

#1 (0,-4)

#2 (5,0)

#3 (3,1)

Explanation:

#1. (-3, 2) (0, y) slope = -2

slope = rise/run therefore slope = -2/1 or down 2 and over 1

so from -3 to 0 you are going over 3 units (or 3 times) Therefore to find y at x=0, you have to move three steps, or 3 times -2 = -6 so 2-6 = -4

so y intercept (b) = -4 0r (0,-4)

#2 (-7,-4) (x,0) slope (m) = 1/3 -7+12=5 x=5

#3 (4,-3) (x, 1) slope (m) = -4 (4/-1) Moving one unit in slope means

-3=4=1 for Y and 4-1=3 for X therefore the point is (3, 1)
