Write the equation in slope-intercept form, identify the slope and the y-intercept.
SashulF [63]

Answer:

Slope is 2; y-intercept is (0,-6)

Step-by-step explanation:

Slope intercept form looks like 3y = 2x - 6

In the equation y=mx+b, M is always the slope, and B is always the y-intercept. Therefore if you look back at the problem the slope number should be in front of the x which makes it 2. Since the y-intercept is always b, y = -6.

Slope or m = 2; y-intercept is (0,-6)

How many 3/4 are in 6?
beks73 [17]
Answer: There are 8 3/4 in 6

You can use a rule of three:
If in 3/4 there is 1 (3/4), How many 3/4 are in 6?:

3/4 → 1
6 → x

x=(6)(1)/(3/4)→
x=6/(3/4)→
x=(6/1)/(3/4)→
x=(6/1)(4/3)→
x=(6)(4)/[(1)(3)]→
x=24/3→
x=8

Answer: There are 8 3/4 in 6
