Because we have x = 3, we can substitute it. But first, let's convert 2x + 4y = 14 into y-slope intercept form.

2x + 4y = 14
Subtract 2x from both sides.
4y = -2x + 14
Divide both sides by 4.
y = -1/2x + 3.5

Now substitute.

y = -1/2(3) + 3.5
y = -1.5 + 3.5
y = 2

How to find slope and y intercept 6x-5y=15?
iogann1982 [59]
We need to put this equation in y = mx + b form because in this form, the slope will be in the m position and the y intercept will be in the b position. So basically, we solve for y.

6x - 5y = 15 ....subtract 6x from both sides
-5y = -6x + 15...divide both sides by -5
(-5/-5)y = (-6/-5)x + (15/-5)...simplify
y = 6/5x - 3

y = mx + b...remember, m is ur slope and b is ur y int
y = (6/5)x + (-3).....ur slope(m) = 6/5 and ur y int (b) = -3

Xelga [282]

Answer:

See below

Step-by-step explanation:

She could have each student in the class write his or her name on a slip of paper and put it in a bowl. Then, she could shake the bowl and pull out any slip of paper with a student's name on it. After 3 times, the random sample would be over, and Mrs. Purdue would have her 3 representatives.
