Answer:

y= $\frac{2}{5}$ x -3

Step-by-step explanation:

slope-intercept form is y=mx+b

m= slope

b= y-intercept

so plugin your numbers with the given data...

and you get y=2/5x-3

For the graph, you start at -3 on the y-intercept and then move right 5 and up 2

Graph is the picture below :)

Which ordered pair is the solution to the system of equations? {x+3y=-12, y= 1/3x-6?

Julli [10]

For this, I'll be using the substitution method. Since y = 1/3x - 6, replace the y variable in the first equation with 1/3x - 6 and solve for x:

$x+3(\frac{1}{3}x-6)=-12\\ x+x-18=-12\\ 2x-18=-12\\ 2x=6\\ x=3$

Now that we have the value of x, plug it into either equation to solve for y:

$3+3y=-12\\ 3y=-15\\ y=-5\\ \\ y=\frac{1}{3}*3-6\\ y=1-6\\ y=-5$

<h3>In short, the solution to this equation is (3,-5).</h3>

Find the value of 2x-yi fx+y=8and4x-y=22

Alexeev081 [22]

Answer:

Step-by-step explanation:

Given

$x+y=8\\ \\4x-y=22$

Add these two equations:

$x+y+4x-y=8+22\\ \\5x=30\\ \\x=6$

Substitute it into the first equation:

$6+y=8\\ \\y=8-6\\ \\y=2$

Then

$2x-y=2\cdot 6-2=12-2=10$
