Solve the following system of equations. What is the y value of the solution?

Svet_ta [14]

Answer:

y = 2

Step-by-step explanation:

x + 5y - 10 = 0

X = 4y - 8

since x is given as = 4y - 8 we can use this in first equation

replace x with 4y - 8

x + 5y - 10 = 0 ➡ 4y - 8 + 5y - 10 = 0 add like terms

9y - 18 = 0 add 18 to both sides of the equation

9y = 18 divide both sides by 9

y = 2

What is the slope of the line passing through the points (0, 4) and (6, 13)

skelet666 [1.2K]

Answer:

The slope is $\frac{3}{2}$

Step-by-step explanation:

Hi there!

We are given the points (0, 4) and (6, 13)

We want to find the slope of the line containing these two points

Slope (m) is the steepness of the line. When calculating from two points, you use the equation $\frac{y_2-y_1}{x_2-x_1}$ , where $(x_1, y_1)$ and $(x_2, y_2)$ are points

Although we have what we need to find the slope, let's label the values of the points to avoid confusion and mistakes.

$x_1=0\\y_1=4\\x_2=6\\y_2=13$

Substitute these values into the equation

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

m= $\frac{13-4}{6-0}$

Subtract

m= $\frac{9}{6}$

Simplify

m= $\frac{3}{2}$

The slope of the line is 3/2

Hope this helps!
