Answer:
2
Step-by-step explanation:
The y-intercept is the point on the graph where the line intersects with the y-axis. Since this point must be on the y-axis the x-value must be 0. Every coordinate on the y-axis has an x-value of 0. So, to find the answer find the y-value when x=0. In this case, when x=0, y=2. Therefore, the y-intercept is 2, also written as (0,2).
Hi,
Work:
Equation;

First add up numbers and distribute 9 over parenthesis.

Second: collect like terms.

Move variable 59p to left side and change its sign.

Then move constant 123 to right side and change its sign.

Calculate the difference.

Divide both sides of equation by 59.

Hope this helps.
