Answer:
please can I get the full picture I can't fully understand
Answer:
see the explanation
Step-by-step explanation:
we know that
The y-intercept is the value of the function y when the value of x is equal to zero
Part 1) we have

For x=0
substitute in the linear equation and solve for y


therefore
The y-intercept is the point (0,-6)
Part 2) Find the y-intercept of the function represented in the graph
Looking at the graph
For x=0
Find the value of y in the graph
The value of y is equal to y=1
therefore
The y-intercept is the point (0,1)
You factor the expression first leaving you with

Then you would cancel out 3xy as because there is exactly one on each side. This, in turn, would leave you with
z - 1
Rearrange the equation to get:
y = 3x - 7
From this you can see that:
m = 3, b = -7
