Analyze the equations in the graphs to find the slope of each equation the y-intercept of each equation in the solution for the

natta225 [31]

Given:

$y=50x+122\ldots\text{ (1)}$ $y=1540-82x\ldots\text{ (2)}$

The general equation is

$y=mx+c$

m is a slope and c is the y-intercept.

From equation (1),

$\text{Slope = 50 and y intercept is 122}$

From equation (2)

$\text{Slope = -82 and yintercept is }1540$

From equation (1) and (2)

Substitute equation (2) in (1)

$1540-82x=50x+122$ $50x+82x=1540-122$ $132x=1418$ $x=\frac{1418}{132}$ $x=44$

Substitute in (2)

$undefined$

How do you use graphs toslove a system of two linear equation

marysya [2.9K]

Answer:

A system of linear equations is a system made up of two linear equations. To solve the system of equations, you need to find the exact values of x and y that will solve both equations. One good way to do this is to graph each line and see where they intersect.

L 5.2.3 Quiz: Two-Variable Systems: Substitution

Misha Larkins [42]

Answer:

We get x=3 and y=21

The ordered pair will be: (3,21)

Step-by-step explanation:

We need to use the substitution method to solve the system of equations.

$y = 10x-9\\y = x + 18$

For substitution method we substitute the value of x or y from one equation to other.

Let:

$y = 10x-9--eq(1)\\y = x + 18--eq(2)$

Putting value of y from equation 2 into equation 1

$y=10x-9\\Put\:y=x+18\\x+18=10x-9\\x-10x=-9-18\\-9x=-27\\x=\frac{-27}{-9}\\x=3$

So, we get value of x=3

Now, for finding value of y, We substitute the value of x

Find value of x from equation 2

$y=x+18\\x=y-18$

Now, putting value of x in equation 1

$y=10x-9\\Put\:x=y-18\\y=10(y-18)-9\\y=10y-180-9\\y-10y=-189\\-9y=-189\\y=\frac{-189}{-9}\\y=21$

So, we get value of y=21

So, We get x=3 and y=21

The ordered pair will be: (3,21)

Identify the graphed linear equation.

prisoha [69]

Answer:

Step-by-step explanation:

I think its A because if you see the line which is the slope, the slope is going up, so its positive. to find the x, you use ride over run. also, you see the y intercept is up and its positive. sorry if I get it wrong.

I hope it helped!!!:)
