Which of the following equations is equivalent to y = 2x +3? O A. y+ 2x = 3
O B. y - 3 = 2(x - 1)
O C. y -2x = 3
O D. y - 3 - 2 + 1)
Hel

y - 2x = 3

Step-by-step explanation:

y = 2x + 3

-2x -2x

y - 2x = 3

b. 2

step-by-step explanation:

the slope of a line =δy/δx

δy= y₂-y₁

δx= x₂-x₁

therefore, using the points (-2,-3)   and (3,7) we can calculate gradient as follows:

m=(7--3)/(3--2) (a number minus a negative number the sign changes to a plus)

m=(7+10)/(3+2)

=10/5

=2
