Answer:
- The value of b is -2.
Step-by-step explanation:
I have solved this with the help of a coordinate plane.
- First, I plotted the point (-2,4).
- Next, I tested the y-intercept and found that the equation of the line that crossed the point is y = -3x - 2.
Now, if we compare the equation and the formula:
- (y = mx + b) = (y = -3x - 2)
We can clearly see that the value of b is -2.
Hence, the value of b is -2.

Answer:
b = -2
Step-by-step explanation:
y=-3x+b
y = -3( x + b/3 )
∵ from this we get gradient is -3.
use formula:
y -y1 = m (x - x1 )
y - 4 = -3 ( x - - 2)
y -4 = -3( x + 2)
y = -3x - 6 + 4
y = -3x -2
if we compare both we get to understand b = -2
