Plzzz 2.-a line has an x-intercept of (4, 0) and a y-intercept of (0, 12). find the slope of the line.3.-a horizontal line includes the points (0, -5 ) and ( 2, -5 ) find the slope of the line.

Problem #1
your going to need two points from the line to solve this. (use #3 as example)

Problem #3

x¹= 0, x²= 2
y¹= -5, y²= -5

Solving for the "y" portion
-5 - -5 = -10

Solving for the "x" portion
2-0 = 2

"y" a portion goes on top, "x" portion goes on bottom making it -10/2 which simplifies to -5.

ANSWER:
The Slope is -5
