Hey just a few questions that i really need with. they've been overdue for a week. .

4. y varies directly with x. When x = 8, y = 24. What is y when x = 10?

If you multiply 8 by 3, you get 24. Because you multiply x by 3 to get y, you can multiply 10 by 3, and you get 30

y is 30.  (second option)

5. Slope intercept form is:

y = mx + b

"m" is the slope, "b" is the y-intercept

Since you know the slope is 2/3, and the y-intercept is 9, your equation is:

y = 2/3x + 9  (third option)

6. You want to find an equation in slope intercept form for the line that passes through the points (1 , -3) and (3 , 1)

y = mx + b

You need to find "m" and "b". To find the slope, you can use the slope formula:

And plug in the points (1, -3) and (3,1)

y = 2x + b

To find "b", you can plug in one of the points into the equation. I will plug in (3,1)

y = 2x + b

1 = 2(3) + b

1 = 6 + b

-5 = b

y = 2x - 5  (fourth choice)
