Answer:

x=9  y=-4

Step-by-step explanation:

1) to eliminate a variable make sure they are the same so you can cancel them out

lets eliminate x

-3 and -2 share a GCF of 6 so

2(-3x-4y=-11)

-6x-8y=-22

3(-2x-6y=6)

-6x-18y=18

-6x-8y=-22

-

-6x-18y=18

--------------------------

10y=-40

y=-4

2)substitute y as -4 in the second equation

-2x-6(-4)=6

-2x+24=6

-2x=-18

x=9

Answer:

(9,-4)

Step-by-step explanation:

(-3x-4y=11)*-2(-2x-6y=6)*3\\6x+8y=22-6x-18y=18\\ 6x and -6x cancel out-10y=40 y=-4     \\Plug -4 for y.  -2x-6(-4)=6                        -2x+24=6                            -24   -24                         -2x=-18                          x =-9

Find the y and the x intercepts of the graph of the equation of y=3x+1
BaLLatris [955]

Answer:

x-intercept ⇨ -1/3

y-intercept ⇨ 1

Step-by-step explanation:

⟺ Finding the x-intercept, substitute y = 0

y=3x+1\\0=3x+1\\3x+1=0\\

Move 1 to subtract the another side.

3x=-1

Then move 3 to divide -1, leaving only x as a subject since we want to find the x-intercept.

x=-\frac{1}{3} #

⟺ Finding the y-intercept, substitute x = 0

y=3x+1\\y=3(0)+1\\y=0+1

y=1 #

Tips:

Here's the tips about finding the intercepts of the graph.

⟺ For x-intercept, It's like solving an equation to find the x-term.

⟺ For y-intercept, It's like using the constant to answer.

As for y = mx+b where m = slope and b = y-intercept.

For a linear function, It's not necessary to substitute x = 0 just to find y-intercept as we can answer the constant as our y-intercept.
