Question

Which equation has a y-intercept at (0,3) and a x-intercept at (-4,0)

Answer 1

Using the two coordinates you can find the equation
------------------------------------
Find slope first
Slope
`= (y2-y1)/(x2-x1)`
0 - 3 = -3
-------
-4 - 0 = -4
--------------------------------------------------
Simplify -3/-4
3/4
-----------------------------------------------------------
Your slope is 3/4 and the Y-intercept as mentioned in the question is "3"
----------------------------------------------------------------------
So your equation is y = 3/4x + 3
