Question

write an equation of the line in slope - intercept form.
(the chart shows a coordinate grid with a line passing through (0, - 2) and (2, 2))
$y = \square$

Explanation:

Step1: Identify intercept and point

Intercept $b=-2$ (from $(0,-2)$), point $(2,2)$

Step2: Calculate slope

$m=\frac{2 - (-2)}{2 - 0}=\frac{4}{2}=2$

Step3: Write slope-intercept form

$y=mx+b=2x-2$

Answer:

$y = 2x - 2$
