To find the slope between two coordinates, you use the formula:
m = y2 - y1/x2 - x1
If coordinate A is (-2, 5) and coordinate B is (3, -4), then:
y2 = -4
y1 = 5
x2 = 3
x1 = -2
So, just substitute the points into the formula.
m = -4 - 5/3 - (-2)
m = -9/5
The slope of the line is -9/5.
Answer:
B. $3100
Step-by-step explanation:
if he's going to pay for his friend. The least expensive dinner menu is $725, for him and his friend it would be $1450. Then for the movie tickets it's $8.00 each, $16.00. $1450+$16.00=$30.50. Round that to the closest whole number, $3100.
Answer:
The equation is 0.11x + 0.25 = 0.15x (I think) and the answer is 6.25 = x
Step-by-step explanation:
0.11x + 0.25 = 0.15x Subtract 0.11x from both sides
-0.11x -0.11x
0.25 = 0.04x Divide both sides by 0.04
6.25 = x
7 + 2x = 51
