@MathFrustration well you're given 2 points of a line.. what do you think you should do first?

anonymous · Answer

y=mx+b?

alexwee123 · Answer

yes good job
 but do you know how to find the variables m and b?

anonymous · Answer

Not really, the teacher never explained how to and the math book never explained it to where you can understand it.

alexwee123 · Answer

hmm ok

alexwee123 · Answer

do you know what m and b stand for then?

anonymous · Answer

Y is the point on the y axis, m is the slope, x is the point on the x axis.

anonymous · Answer

Also known as the y-intercept and the x-intercept.

alexwee123 · Answer

anonymous · Answer

Plugging the points into x and y first.

alexwee123 · Answer
