Question

write the equation in slope-intercept form from the given points (5,-5) and (0,-1)​

Answer 1

Answer:

First, we must find the slope of the line using slope formula.

$m = \frac{-1 + 5)}{0 - 5} = \frac{4}{-5} = -\frac{4}{5}$

Second, we must find the y-intercept, given the slope we found.

$-5 = -\frac{4}{5}(-5) + b\\\\-5 = -4 + b\\\\-1 = b$

Finally, we can set an equation of this line.

$y = -\frac{4}{5}x - 1$
