Question

Convert the following equations from point-slope form to slope-intercept form.

9) y – 4 = 3(x – 1)

10) y – 1 = -4(x – (-3))

Answer 1

Answer:

We need to solve both for y.

#9:

$y - 4 = 3(x - 1)\\\\y - 4 = 3x - 3\\\\y = 3x + 1$

#10:

$y - 1 = -4[x - (-3)]\\\\y - 1 = -4(x + 3)\\\\y - 1 = -4x - 12\\\\y = -4x - 11$
