Question

Find an equation of the line that goes through the point (2,1) and has a slope of 4. Leave equation in point-slope form

Answer 1

We need a graph to figure this out.

Answer 2

ok well your slope is 4 so your trying to get y=mx+b! so plug in your 4 into the m then your X value into the X and the Y and into the Y so it should be 1=4(2)+b then multiply 4 and 2 then subtract 8 and get b=-7 then put it back so it is y=4x-7

Answer 3

I got 2-1= m(3-2) thats not right?

Answer 4

no

Answer 5

point slope form is

y-y1 = m(x-x1)

In your case, m = 4, x1 = 2 and y1 = 1
