Answer:

B

Explanation:

The equation of a line in slope- intercept form is

y = mx + c ( m is the slope and c the y- intercept )

Here m = 4

The only 2 equations with a slope of 4 are

B y = 4x - 5

C y = 4x + 2

To find the one which contains the point (2, 3)

Substitute x = 2 into the equation and if y = 3 then the line contains the point

B y = 4(2) - 5 = 8 - 5 = 3 ← contains (2, 3 )

C y = 4(2) + 2 = 8 + 2 = 10 ≠ 3 ← does not contain the point
