Answer:
a
using a calculator u can see the digits that follow.
Use the points and do y2-y1 divided by x2-x1
You will get -2 which is the m (slope)
Substitute one of the points into the y and x to get the b (y-intercept)
You will get -6
Put everything into the equation
y=-2x-6
If i do my calculations it will be the price of 2.66
A right angle has 90 degrees, so 90 divided by 6 = 15 degrees
