a line passes through the points (-4, -19) and (12, -7). write its equation in slope - intercept form. write your answer using integers, proper fractions, and improper fractions in simplest form.
Answer
Answer:
$y=\frac{3}{4}x - 16$
Explanation:
Step1: Calculate the slope
$m=\frac{y_2 - y_1}{x_2 - x_1}=\frac{-7-(-19)}{12 - (-4)}=\frac{-7 + 19}{12 + 4}=\frac{12}{16}=\frac{3}{4}$
Step2: Use point - slope form
$y - y_1=m(x - x_1)$, using the point $(12,-7)$ and $m = \frac{3}{4}$, we have $y+7=\frac{3}{4}(x - 12)$
Step3: Convert to slope - intercept form
$y+7=\frac{3}{4}x-9$, then $y=\frac{3}{4}x - 16$
