Find the slope of a line that passes through the points (-3, -1) and (2, -1)

Answers

Answer:

[tex]\frac{0}{5}[/tex]

Step-by-step explanation:

In order to find the answer to this question you need to input the values in a slope formula and solve using KCF (Keep, Change, Flip) if needed.

[tex]m = \frac{y^2-y^1}{x^2-x^1}[/tex]

[tex](-3,-1),(2,-1)[/tex]

[tex](x^1,y^1)=(-3,-1)[/tex]

[tex](x^2,y^2)=(2,-1)[/tex]

Substitute:

[tex]m=\frac{-1--1}{2--3}[/tex]

Solve using KCF:

[tex]-1+1=0[/tex]

[tex]2+3=5[/tex]

[tex]=\frac{0}{5}[/tex]

Hope this helps.

Which equation represents the line that passes through the points (-3;7) and (9,-1)

Answers

Answer:

[tex]y = - \frac{2}{3} x + 5[/tex]

Step-by-step explanation:

[tex]y = mx + b[/tex]

finding the slope m of the line using the above points

[tex] m = \frac{y2 - y1}{x2 - x1} = \\ \frac{ - 1 - 7}{9 - - 3} = \frac{ - 8}{9 + 3} = - \frac{8}{12} = - \frac{2}{3} [/tex]

substitute the slope and one of the points into the y-intercept form to solve for b

[tex]y = mx + b \\ 7 = - \frac{2}{3} ( - 3) + b \\ 7 = \frac{6}{3} + b \\ 7 - 2 = b \\ b = 5[/tex]

therefore the answer to the question is

[tex]y = - \frac{2}{3} x + 5[/tex]

. Let g(x) = 3x2 + 4X – 36. What is g(2)?

Answers

Answer:

Step-by-step explanation:

The notation means that wherever you see an x on the right, you let it equal 2.

g(x) = 3x^2 + 4x - 36

x = 2

g(2) = 3*2^2 + 4*2 - 36

g(2) = 3*4 + 8 - 36

g(2) = 12 + 8 - 36

g(2) = 20 - 36

g(2) = - 16

Answer:

603

Step-by-step explanation:

First divide to get unit rate:

737/11= 67

Then  multiply:

67*9= 603

Hope this helps! :)

Answer:

Scott would drive 603 miles in 9 hours

Step-by-step explanation:

First to find the rate we need to see how many miles Scott can drive per hour.

737/11=67

67/1 or 67 mph is our unit rate.

so if we want to know how many miles he can drive per 9 miles we just multiply (the unite rate by how many miles) 67 x 9, which equals, 603.
