Question

Which is an equation of the line with a slope of (1,4) and a y-intercept of-2​

Answer 1

y=6x-2

Explanation:

Fisrt things first, you want to find the slop. One of the points is (1,4). You want the other point. Using the y-int, you can figure out the other point is (0,-2). You get this because the y-intercept means the x value is 0.

Next you use the two points and plug it into the formula (change in y/ change in x)

(-2-4)/(0-1)=-6/-1 = 6

Now you know the slope is 6. Since you know the y-int, you can plug that into the slope-intercept formula (y=mx+b)

That would give you: y=6x-2
