Simone claims that the slope of the line through (-2, 7) and (3, 0) is the same as the slope of the line through (2, 1) and (12,

JulijaS [17]

Answer:

Simone is correct

Step-by-step explanation:

Given

Line 1:

$(x_1,y_1) = (-2, 7)$

$(x_2,y_2) = (3, 0)$

Line 2:

$(x_1,y_1) = (2, 1)$

$(x_2,y_2) =(12, -13)$

Required

Is Simone correct?

Slope (m) is calculated using:

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

For Line 1

$m = \frac{0 - 7}{3 - (-2)}$

$m = \frac{0 - 7}{3 +2}$

$m = \frac{-7}{5}$

$m = -\frac{7}{5}$

For Line 2:

$m = \frac{-13 - 1}{12 -2}$

$m = \frac{-14}{10}$

Divide by 2/2

$m = \frac{-14/2}{10/2}$

$m = \frac{-7}{5}$

$m = -\frac{7}{5}$

By comparison, both lines have the same slope.

Hence, Simone is correct

Help me solve for q!<br><br> 21 + 3q < 3 (13 - q)<br><br> How do you solve it? Thank you!

Molodets [167]

Good morning

21 + 3q < 3(13 - q)
21+ 3q < 39 - 3q Here it was -3q and it was on the left side. However when you are switching it to another terms that looks like it you must change the sign as well.
3q + 3q < 39 - 21 Here I bring the common terms together.
6q < 18
Divide both sides by 6
6q/6 < 18/6
q < 3
