1 is D, because if you wrote out all the choices as equations, you would get that A is 1/2 n - 3, B is also 1/2 n - 3, C is 1/2 - 3, and D is 1/2(n - 3)

2 is A, because 3 times her age minus 4 is 3x-4, with x as Marcys age

3 is C, because although 11 x 5 is 55, it says that 5 times a number is LESS than 55, so the answer is 10, or C

4 is B because the mode is 92, the mean is 122, and the median is 88, which would mean that mean>mode>median

Put the following equation of a line into slope-intercept form, simplifying all
Maurinko [17]

Answer:

y=-4/5 x + 7

Step-by-step explanation:

Subtract 8 x by 8 x. Do not put 8 x under 10 y or 70.

Then divide 10 by all of the terms.

Then you have: y= 7  - 8/10 x

But then you have to flip 7 and - 8/10 x

And get y= -8/10 x + 7

Simplified is y= 4/5 x + 7

REMEMBER: y=m x + b

M= Slope

B= y-intercept
