Form that has a slope of 1/3 and a y-intercept of (0,-6)

The slope-intercept form:

y = mx + b

m - slope

b - y-intercept

We have the slope m = 1/3 and the y-intercept (0, -6) → b = -6

1. find the coordinates of b, c, e and f
b(-2,4)
c(1,1)
e(4,4)
f(6,2)

2. use the formula:
m=y2-y1/x2-x1

3. slope of bc
m=1-4/)
m=-3/3
m=-1

4. slope of ef
m=2-4/6-4
m=-2/2
m=-1

5. so both of the line segments have the slope of -1, have a nice day : d
