Answer:

Step-by-step explanation:
Use the slope-intercept formula:
where m is slope and b the y-intercept.

Use the slope formula for when you have two points:

Rise over run is the change in the y-axis over the change in the x-axis. Insert values:

Simplify parentheses (negative+negative=positive)

Simplify

2 is the slope:

Now use one of the points to find the y-intercept by substituting the x and y values into the equation. Solve for b:
(4,7)


The y-intercept is -1. Insert into the equation. Change the + symbol to -:

Done.
Answer:
True
When you add two negative numbers the sum is always negative ex.
When you add two numbers with different signs get the difference and get the sign by the larger absolute value ex.
Step-by-step explanation:
Answer:
B.) y - 6 = -8/5(x + 2)
Step-by-step explanation:
Remember in order to find the slope intercept form on 2 points, you need these equations:
and 
To find the slope, you will need to use the first equation. In this case the equation will look like this: 
Then use the second equation, plug in the numbers, and you will get B as your answer
