Question

Two equations y=3/4x+1 and y=1/2x+b. They intersect at (4,2) what is b

Answer 1

b = 0

Explanation:

Since,the equations y=3/4x+1 and y=1/2x+b intersect at (4,2)

So, plug x = 4 and y = 2 in equation y=1/2x+b, we find:

`2 = (1)/(2) * 4 + b \\ \\ 2 = 2 + b \\ \\ 2 - 2 = b \\ \\ \purple{ \bold{ b = 0}}`
