Answer:

Step-by-step explanation:

The slope-intercept form of an equation of a line:

$y=mx+b$

m - slope

b - y-intercept → (0, b).

The formula of a slope:

$m=\dfrac{y_2-y_1}{x_2-x_1}$

We have the points A(0, -4) → b = -4 and B(6, 2).

Calculate the slope:

$m=\dfrac{2-(-4)}{6-0}=\dfrac{6}{6}=1$

Put the value of m and of b to the equation:

$y=1x-4$ <em>add 4 to both sides</em>

$y+4=x$
