Please I really need help!!!

For the line in red

The slope is  6/3 or 2

The y-intercept is negative 2

Equation is y = 2x - 2

For the line in blue

Slope is 4/2 or 2

Y-intercept is 3

Equation is y = 2x + 3

Step-by-step explanation:

I found slope by how many units you have to go up to get to the other point which is y to how many units you have to get horizontally to get to that point which is x. I found the y-intercept just by looking where the line met the x-axis. Lastly, I found the equation just by plugging everything in. This is because the equation is y = mx + b. For m you put in the slope and for b you put in the y-intercept.

Hope this helps!

f(x) is going down by 4
