Question

Find the value of b if the graph of the equation y = -5x + b goes through the G(4,3) point.

Answer 1

We know that x = 4 and y = 3, so plug those in into the equation
3 = -5(4) + b
3 = -20 + b
add 20 on both sides
23 = b

Answer 2

The Value of b is 23

Explanation:

substitute 4 for x, and 3 for y. Then move combine like terms.

3 = -5(4) + b

3 = -20 + b

23 = b
