Answer:
3.) [tex]y = \frac{2}{5} x - 7.2[/tex]
4.) [tex]y = -3x - 1[/tex]
Step-by-step 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 = [tex]\frac{2}{5}[/tex] (-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.
