The slope-intercept form:

$y=mx+b$

m - slope

b - y-intercept → (0, b)

We have the points (-4, -6) and (2, 6). Substitute:

$m=\dfrac{6-(-6)}{2-(-4)}=\dfrac{12}{6}=2\\\\y=2x+b$

Put the coordinates of the point (2, 6) to the equation of a line:

$6=2(2)+b\\\\6=4+b\qquad|-4\\\\2=b\to b=2$

<h3>Answer: y = 2x + 2</h3>
