What is the equation of the line through (0, -4) and (3, 2)?

Explanation:
To find the equation of a line through two points, start by finding its slope: m = (change in y) / (change in x). Between (0, -4) and (3, 2), the slope is (2 - (-4)) / (3 - 0) = 6/3 = 2. With this slope, use the slope-intercept form y = mx + b and plug in one point to find b. Using (0, -4): -4 = 2(0) + b, so b = -4. The line is y = 2x - 4. This passes through both given points: at x = 0, y = -4; at x = 3, y = 2. The other options either have the wrong slope or the wrong intercept, so they don’t fit both points.
