Answer:

Green Graph: y = x - 6

Red Graph: y = -3/2 + 7

Explanation:

Slope intercept form is represented by the formula:

y = mx + b

m is your slope

b is the y intercept

Another thing to note is that, when m is negative, the graph will point to the left, while when m is positive in will point in the right

For the green graph, the line intercepts at -6, so that will be your b value.

the slope is positive 1 because if your count up from -6 and count across to point (1,-5) you get 1/1

Put these pieces of information in your formula and you get

y = x - 6

You can use the same process to find the equation of the red line. However, the slope will be negative since the graph is pointing to the left side of the coordinate plane.
