Answer:
The equation of line is:

Step-by-step explanation:
We are given that a graph is a that passes through two points:
and 
We know that the equation of line passing through two points:
and
is given by:

Here we have:
and 
Hence, the equation of line is:

Hence the equation of line is:

Answer:
a) Slope is -4/3 y-intercept is 2
b) Slope is 2 y-intercept is -1
Step-by-step explanation:
y=mx+c
m=gradient (or in this case slope)
c=y-intercept
Is this the image? If so, sorry I can't do this lol
Answer:
All of them
Step-by-step explanation:
A y-intercept is the point where a line or curve crosses the y-axis of a graph. Example: (0, 7) (0, 6)
