Question

Write the equation for each line in slope - intercept form:Y int: 4 and goes through (1,8)

Answer 1

Okay, here we have this:

Considering that the slope intercept form is the following:

y=mx+b

If we replace with the provided info we obtain the following:

8=m(1)+4

And here we can clear for the slope (m):

8=m(1)+4

8=m+4

m=8-4

m=4

With this slope we can replace in the slope intercept form and finally we obtain the following equation:
