and improper fractions. Simplify all fractions.

Answer 1

Hi Jewel, leave a comment if you want more explanation of the following:

Explanation:

point-slope formula: y-y1 = m(x-x1)

slope-intercept formula: y = mx + b

using point-slope: y-9 = 1/2(x-(-4))

= y-9 = 1/2(x + 4)

= y -9 = 1/2x +2

we've almost made it to slope-intercept from , notice, but the problem says to leave it in point-slope form, so there you go :) and leave a comment if you need more explanations :)
