Question

13. Write an equation in slope-intercept form of the line that passes through the points (4.2) and (1.-7).​

Answer 1

The answer is
`y=3x-10`

Explanation:

You use the formula
`y_(2) -y_(1) /x_(2) -x_(1)`

Which will give you 3. So the slope is 3/

Then you continue with the equation-
`y=mx+b` (m represents the slope which is 3) We use then use any point but I used (4,2) to plug into the equation.

After using that equation, you get the y-intercept as -10. So, the equation is
`y=3x-10`
