can someone please help me out with this? i’m struggling. (please help me answer 3,4, and 5.) i’ll mark you has brainlist !

ok, here goes...

Step-by-step explanation:

always remember mx + b where

m = slope (remember slope = rise over run which is (change in y/change in x))

and

b = y-intercept

3) m = 3 Why? Line passes through (0, -2) and (1, 1), so the change in y is +3 (from -2 to 1) and the change in x is +1 (from 0 to 1).

3) b = -2 (the point where the line crosses the y axis)

3) f(x) = 3x + (-2) or more commonly 3x - 2

4) m = -1/3 Why? Line passes through (0, 4) and (3, 3), so the change in y is -1 (from 4 to 3) and the change in x is +3 (from 0 to 3).

4) b = 4 (the point where the line crosses the y axis)

4) f(x) = -1/3x + 4

5) m = 0 Why? Line passes through (0, 2) and (1, 2), so the change in y is 0 (from 2 to 2) and the change in x is 1 (from 0 to 1). This results in a slope of 0/1, which yields a 0. This makes sense when you realize a flat line has no slope to it.

5) b = 2 (the point where the line crosses the y axis)

5) f(x) = 0x +2 or just f(x) = 2

the battle of gettysburg is considered the "high water mark" of the confederacy because it marked the greatest advance of the confederate forces against the union.
