find an equation of the line having the given slope and containing the give points. m=5, (2, 1)

Answer 1

B = y - mx = 1 - 2*5 = 1-10 = -9

y = 5x-9

Answer 2

You have m, x and y so just substitute these values in the general formula for a line y= mx+b to solve for b

1=5(2) +b

b=-9

So equation is y= 5x-9
