I can't read the questions even after they are magnified. I have an idea, and I may be able to help you after, but you should do this: 

Use the snipping tool to copy the answers down, then you should post. 

I may be able to help you then if you share with the picture that way. Hope I was a little help!

Choose a method you prefer to solve for a system of linear equations.<br> 2x + 4y = -4<br> 2x-y=6
Artyom0805 [142]

Answer:

Elimination

x = 2

y = -2

Step-by-step explanation:

Elimination

2x + 4y = -4

2x - y = 6

Subtract the second equation from the first

5y = -10

Divide both sides by 5

y = -2

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

Substitute for y = -2 in the second equation

2x - -2 = 6

2x + 2 = 6

subtract 2 from both sides

2x = 4

Divide both sides by 2

x = 2

Which function below has the lowest y intercept? f(x) graph going through (0, 5) and (2, 1) g(x) Kyle started the summer having
mr Goodwill [35]
First find the slope of f(x).

m=(y2-y1)/(x2-x1)

m=(1-5)/(2-0)

m=-4/2

m=-2

y=-2x+b, using (2,1) we can solve for the y-intercept, "b"

1=-2(2)+b

1=-4+b

5=b

y=-2x+5

So f(x) has a y-intercept of 5

g(x)=6m+3

So g(x) has a y-intercept of 3

h(x)=3x+4

So h(x) has a y-intercept of 4


Then g(x) has the lowest y-intercept of just 3.
