Question

Please help me with my work

Answer 1

3.)
`y = (2)/(5) x - 7.2`

4.)
`y = -3x - 1`

Explanation:

You have to find the y-intercept in both questions to put it in point-slope form. The first step is to substitute y and x from the question into point slope-form. You get -6 = m(-3) + b. Then you substitute for the slope which is 2/5. You end up with -6 =
`(2)/(5)` (-3) + b. Solve for b which is -7.2 and put the slope and y-intercept into the final point-slope equation. You follow the same steps for question 4.
