Aline that includes the point (7,4) and has slope of 8

So I assume you are trying to find the equation of the line.

So you are gonna use this equation:

y=mx+b

So the x and y are your x and y coordinate pair and the m is the slope. So now you just substitute and solve for b:

4=8(7)+b

4=56+b

subtract 56 on both sides

-52=b

so now lets plug this into the equation of the line:

y=8x+(-52)

hope this helps!

a.

step-by-step explanation:

step 1 distribute 2 to every term in the parentheses

step 2 add 10 on both sides of the equal sign
