Question

Write an equation in slope-intercept form for the line that satisfies the following condition.
passes through (13, 9) and (30, 26

Answer 1

you need a point and a slope.

So to get the slope do (y2-y1)/(x2-x1), then choose either point to use.

Then plug into point-slope form and solve for y. y-y1=m(x-x1)

so: (26-9)/(30-13)=1
and y-9=1(x-13)
solving for y, the answer is y=x-4
Check by plugging your given points back in.
