Answer:

y=3x-4

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, it is (0,-4). For this form, the 0 in (0,-4) is ignored, and we consider the y intercept to be -4.

So, m is 3, and b is -4. Substitute the values into the equation

y=3x+ -4

y=3x-4

So, the equation in slope intercept form is

y=3x-4
