Find the equation of the line that goes through 41 with a sl

Solution

y=mx+b

where m is slope and b is y intercept

m is given to be 5

So

y=5x+b

Now to find b , lets plug in the point given

-1 = 5(4) +b

-1 = 20 +b

Subtract 20 from both sides

-21 =b

b=-21

So the equation becomes

y=5x -21
