Question

Find the y intercept (-3,19) and (6,13)

Answer 1

Explanation:

We will first find the slope of the line from those 2 points, then write the equation of the line in slope-intercept form, solving for b, the y-intercept.

`m=(13-19)/(6-(-3))=-(6)/(9)=-(2)/(3)`

So the slope is -2/3. We will choose a point now to use in the slope-intercept equation. I'm picking the one with no negatives (cuz who likes negatives!?).

`13=-(2)/(3)(6)+b` which simplifies down to

13 = -4 + b so

b = 17

The y-intercept of the line that goes through those 2 points is (0, 17)
