Question

Write the equation of a line that passes through (-2,6) and (2,14)in slope intercept form?

Answer 1

First, let's find the slope, which is the change in y divided by change in x. So, this is 8/4, which is 2.

So, the equation is y = 2x + b.

Now, let's plug in one of the points to get the y intercept.

So, the equation is now this: 14 = 2(2) +b
Solve for b: 14 -4 = b
10 = b
So, the equation is y = 2x + 10

Hope this helps!
