Question

Find the value of b if it is known that the graph of y=−3x+b goes through the point (-2,4).

A) 10
B) 7
C) 1
D) -10

Answer 1

To find the value of b, substitute the point (-2,4) into the equation y = -3x + b and solve for b. The value of b is -2.

Step-by-step explanation:

To find the value of b, we need to substitute the given point (-2,4) into the equation y = -3x + b and solve for b. Here's how:

Substituting the x-coordinate (-2) and y-coordinate (4) into the equation:

4 = -3(-2) + b

Simplifying:

4 = 6 + b

Subtracting 6 from both sides:

-2 = b

Therefore, the value of b is -2.
