Answer:

Step-by-step explanation:
First you can find the slope of the line that would pass through those two points using the formula:
m = 
m = 
m=5/4
Now you can just plug the slope and one of the points into point-slope form for an equation of the line that will pass through both points. You can choose either point here: I'll just use the first one.
So,

(don't leave out the parentheses!)
Answer:
Step-by-step explanation:
It's easier to convert the angle into degrees.
5π/8 ≅ 112.5°, which is in quadrant II
Solve for a by simplifying both sides of the equation, then isolating the variable.
a = -1 -2n/3 -p
Answer:
Brainleist! I need points see below
Step-by-step explanation:
-2y+1=7
-2y = 6
y = -3
now plug in
9 (-3) - 7
-27-7
-34
Need points! Because this useless mod deleted my answers for no reason
