Question

What is an equation of the line with slope -4/5 and y-intercept 7?

Answer 1

Answer:

The equation's formula:

$y - y1 = m(x - x1)$

Remember that y intercept's x coordinate=0

So:

$y - 7 = - \frac{4}{5} (x - 0) \\ y - 7 = - \frac{4}{5} x \\ y = - \frac{4}{5} x + 7 \: or \: y = - 0.8x + 7$

Good luck!
