Answer:

Step-by-step explanation:
The y-intercept is where the line itersects the y-axis, which is the dark vertical line. This is -8 represented as the constant in the equation.
To find the slope, find the rise over run. Every time the line goes over 1 it goes down 6, so the slope would be -6.
Answer:
1.6
Step-by-step explanation:
Lets count how many points are x and y away from each other since we dont have a graph.
X and Y points:
35-15=20
56-24=32
Use the formula:

32/20 = 1.6
