Question

What equation has a slope of 2 and goes through the point (3, 2)?

Answer 1

Answer:

y = 2x - 4

Step-by-step explanation:

We'll write our equation in y = mx + b form, with m being the slope and b being the y-intercept. We already know our slope, so we can replace m with 2 like this: y = 2x + b. But we don't know what b is. We can use the point (3, 2) to figure out b's value, since it has an x-value (3) and a y-value (2):

2 = 2(3) + b

2 = 6 + b

-4 = b

So we have y = 2x + (-4), or y = 2x - 4.
