What is the slope of the line passing through the points

Bingel [31]

Hello!

Answer:

$\boxed{2}$

Step-by-step explanation:

$Slope=\frac{Y_2-Y_1}{X_2-X_1}=\frac{RISE}{RUN}$

$\frac{1-(-5)}{4-1}=\frac{6}{3}=2$

Therefore, the slope is 2, which is our final answer.

Hope this helps!

Have a nice day! :)

Thank you!

Y=-x+1 23 = 5y - 4x How do I find x and y by using substitution?

Evgesh-ka [11]

Answer:

x = -2 y = 3

Step-by-step explanation:

Equation 1: y = -x + 1

Equation 2: 23 = 5y -4x

Take and plug in what y equals (from equation 1) into equation 2

23 = 5(-x+1) - 4x

23 = -5x + 5 - 4x

23 = -9x + 5

18 = -9x

x = -2

Then plug the -2 in to the first equation for x

y = -(-2) + 1

y = 2 + 1

y = 3
