Y=mx+b
b=y intercept
m=slope
yintercept is where the line crosses the y axis
looks like it crosses at -2
y=mx-2
take a point
how bout (1,0)
x=1
y=0
0=m(1)-2
add 2
2=m
the equation is
y=2x-2
Answer: 10 * 10*10
Step-by-step explanation:
Answer: two over three
Step-by-step explanation:

line intercepts y at (0,-2)
Therefore, 
Substitute x = 3 in y =ax-2

To find the x-intercept, y = 0

The slope is 2/3
y-intercept is -2
So two over three
