Answer:
y = [tex]\frac{2x}{5} + 9[/tex]
Step-by-step explanation:
The formula for the equation of a line is y = mx + b, where m is the slope and be is the y-intercept. We have everything we need except for the b, which is the y intercept. WE have the point (5,7) were x = 5 and y =7 and m = (-2/5) substituting these into the equation will give us that b = 9
After substituting the slope of m and b into the equation, we get the equation above.
