Question

Number 17.

If the y-intercept is 5, what is the value of B of the graph of 2x + By = 15?

A. 0

B. 7.5

C. 1

D. -3

E. 3

Answer 1

Now consider the point (0,5) which is part of graph because the gave that the Y intercept is 5 which means the graph intersects the Y-axis at (0,5).

Now, substitute (0,5) in given equation of the graph. Which is,

2(0) + B(5) = 15

5B = 15

B = 3
