Question

Can you check these please? Thank you!

Identify the correct slope and y-intercept of the equation 5x - 3y = -6

slope = 5/3; y-intercept = (0, 2)

slope = -5; y-intercept = (0, -6)

slope = -3/5; y-intercept = (0, 2)

slope = 5/3; y-intercept = (0, -6)

I have know idea about this one I think it's B but for some reason this one really confuses me.

Use the distributive property to simplify the expression below:
-4(3u - 5)

-12u - 5

-12u + 20

-12u - 20

-12u + 9

I think it's B

Solve: 6x - 2 > 8x + 4

x > -3

x -3

x < -3

x -3

I think C.

Answer 1

problem no. 2 and 3 are correct. Problem No. 1 is not

Answer 2

for problem no.1 you are given the equation of a line in the standard form which is

Ax + By = C

This you have to convert to Slope-Intercept Form which is

y = mx + b, where m = Slope and b = y-intercept.

Can you do that? Change the standard form to slope-intercept form.

Answer 3

I don't know I'm horrible at slopes could you help me a bit more?

Answer 4

we are not doing anything with slopes per se. All you are doing is solving the given equation for y. You are given an equation 5x -3y = -6

This equation you have to solve for y. meaning you have to isolate the y and rewrite the whole equation as y = "something" . Can you do that?

Once you do that we can identify the slope and y-intercept from the resulting equation.

Answer 5

Okay thank you.

Answer 6

Would it be A?

Answer 7

for #1, you have to put it in " y = mx + b " form and m would be the slope and b would be the y-intercept.
Lets do that.....
5x - 3y = -6 (you want -3y on one side and everything else on the other side)
-3y = -5x - 6 (now you want to divide by -3 to get y by itself)
y = 5/3x + 2
slope being 5/3 and y-intercept being 2

-4(3u - 5)
you distribute the -4 through
-4 * 3y + -4 * -5 =
-12y + 20

6x - 2 > 8x + 4
you want to get the x's on one side, so first add 2 to both sides
6x - 2 + 2 > 8x + 4 + 2 (combine like terms
6x > 8x + 6 (now you want to subtract 8x from both sides)
6x - 8x > 8x - 8x + 6 (combine like terms)
-2x > 6 (now you have to divide by -2, keeping in mind when you divide by a negative, the inequality sign changes)
-2x/-2 < 6/-2
x < -3

any questions ?
