Question

Use the linear equation, y = mx + b and solve for B (the y-intercept).

y = -9/-13x + ____


Slope = -9/-13

Endpoint = 7,-6

Answer 1

`b=-(141)/(13)`

Step-by-step explanation:

Given the following question:


`y=mx+b`

In order to find the answer, we substitute the given information into the slope intercept then solve for b.


`y=mx+b`

`m=(-9)/(-13)`

`y=-6`

`x=7`

`(7,6)=(x1,y1)`

Substitute:

`-6=(-9)/(-13) (7)+b`

`(-9)/(-13) *(7)/(1) =(63)/(13)`

`(63)/(13)+b=6`

`(63)/(13) -(63)/(13) =0`

`6-(63)/(13) =-(141)/(13)`

`b=-(141)/(13)`

Hope this helps.
