Question

Slope-intercept form, write the equation of the line

that passes through the point (4, 2) with a slope of 5.

Answer 1

`y=5x-18`

Explanation:

Given the following question:

Point A = (4, 2) = (x, y)
Slope = 5

To find the answer we are going to have to use the formula for slope intercept, substitute the values, then solve for the variable b to have our answer.


`y=mx+b`

`y=2`

`m=5`

`x=4`

`2=5(4)+b`

`5*4=20`

`2=20+b`

`20-20=0`

`2-20=-18`

`-18=b`

`b=-18`

`y=5x-18`

Your answer is "y = 5x - 18."

Hope this helps.
