Answer: -2 - (-7)
Step-by-step explanation: They both have the same outcome, 5. Which one is negative and one is positive. The last option is correct.
Answer:
Step-by-step explanation:
The point slope formula is y - y1 = m(x - x1)
the value x1 is the x coordinate of a point
the value y1 is the y coordinate of a point
the value m is the slope, which is 3
therefore, x1 = -2 & y1 = 1
Then, all you do is plug in the points:
y - 1 = 3(x + 2)
NOTE: It is 3(x + 2) instead of 3(x - 2) because the formula is (x - x1). If you plug x1 in, it is (x - (-2)). 2 negatives cancel out to be a positive, so it is (x + 2)
Answer:
slope = - 
Step-by-step explanation:
Calculate the slope m using the slope formula
m = 
with (x₁, y₁ ) = (23, - 30) and (x₂, y₂ ) = (- 7, 18)
m =
=
=
= - 
-1(1)=(2)-1 because you replace x with one since there is no number in front then you solve -1=-2 but make sure to multiply those four #'s
