Answer:

A. y = [tex]-\frac{4}{5}[/tex]x + 7

Step-by-step explanation:

Slope intercept form is y = mx + b where m is the slope and b is the y-intercept

It gives us the slope, so we can plug that in: y = [tex]-\frac{4}{5}[/tex]x + b

Next, it gives us a point, so we can plug in the x and y into our equation and solve for b when (x, y)

y = [tex]-\frac{4}{5}[/tex]x + b

7 =  [tex]-\frac{4}{5}[/tex](0) + b

7 = b

Last, complete our equation:

y = [tex]-\frac{4}{5}[/tex]x + b

y = [tex]-\frac{4}{5}[/tex]x + 7
