Passes through (0,4) and a slope of -3. Write in slope-intercept form and in the standard form.

Question

please help I'm literally so bad at math ;-;

Answer 1

(0,-4) IS the y-intercept, which happens when x=0...

so B=-4

otherwise, you can use the intercept formula:

B = y - mx = -4 - (-3)(0) = -4 - 0 = -4

y = mx + b = -3x + -4 = -3x-4
