Answer:
A
Explanation:
Always start by finding the slope when you're given two points! (This means that we can rule out C and D.) The equation for slope is
You can remember this by thinking about it being rise over run, or the distance you go up or down divided by the distance you go across. This means that answer choices B and D are incorrect.
Next, what do we plug into slope-intercept form to get the y-intercept? The slope, and one other point.
y = mx+b
You can see that if we were to plug in m, x, and y, we'd only have b left, and we could solve!
This means that choice A is correct.
