please help me it dues in 16 minutes is this right?

Answer:
Yes
Step-by-step explanation:
Slope intercept form is:
y=mx+b
where m is the slope, and b is the y intercept
We are given the slope, it is -3. We are also given the y intercept, (0,4). In this form, the 0 in (0,4) is ignored, and our y intercept is considered to be 4.
Therefore, m is -3, and b is 4.
y=mx+b
y=-3x+4
So, your answer is correct.
Answer:
Yes
Step-by-step explanation:
y = mx + c
m = -3
c = 4
y = -3x + 4
