Find the slope of the line passing through the points (6, -6) and (4, -4)
djyliett [7]

To find the slope (m), use the slope formula:

m=\frac{y_2-y_1}{x_2-x_1}         and plug in the two points

(4, -4) = (x₁, y₁)

(6, -6) = (x₂, y₂)

[lines usually go from left to right, so the point furthest to the left is the 1st point]

m=\frac{y_2-y_1}{x_2-x_1}

m=\frac{-6-(-4)}{6-4}   [two negative signs cancel each other out and become positive]

m=\frac{-6+4}{6-4}

m=\frac{-2}{2}

m = -1

Evaluate 15 + |-3| - 4
hichkok12 [17]

Answer:

14

Step-by-step explanation:

we are solving 15 + |-3| - 4

anything inside |   | means it's absolute value.

absolute value means that even if it is a negative number inside, it will change to positive. if it is a positive number inside, it will stay the same.

so |-3| is 3.

15 + 3 - 4

18 - 4 = 14.

we got the answer
