Answer:

The answer is [tex]y=3x-10[/tex]

Step-by-step explanation:

You use the formula [tex]y_{2} -y_{1} /x_{2} -x_{1}[/tex]

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

Then you continue with the equation-  [tex]y=mx+b[/tex] (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 [tex]y=3x-10[/tex]
