Question

If an equation of a line is y - 5 = m(x-2) and (1,1) is a point on the graph, what is m?

Answer 1

m = 4

Explanation:

Substitute x = 1, y = 1 , that is(1,1) into the equation

1 - 5 = m(1 - 2)

- 4 = - m ( multiply both sides by - 1 )

m = 4

Answer 2

m=4

Explanation:

given equation is

y-5=m(x-2)

put given point in above equation

1-5=m(1-2)

-4=m(-1)

-4=-m

m=4
