Answer:

14. D

15. A

16. A

Step-by-step explanation:

14. Point slope form formula: y-y₁=m(x-x₁).

When graphing you always want to think x/y for your slope.

X-axis increases by 2 and the Y-axis increases by 10, which would make the slope (m) 2/10 = 1/5.

If your slope is does not come out correct, then you can prove your point.

15. The given information is (-2,2): m=-1.

Given the Point slope formula: y-y₁=m(x-x₁), you can replace m to -1, y₁=2 and x=+2. (Two negatives would make a positive.)

Your answer: y-2=-(x+2)

16. Given: y=4x-7; (3,0)

Parallels lines: Same slope different y-intercepts.

A and D has the same slope and different y-interecepts, but your answer would be A because the equation that was given as a negative y-intercepts.

If the m angle 2 = 113 what is the angle 6

dmitriy555 [2]

m < 6 = m < 2 because they are corresponding angles

So m < 6 = 113 degrees answer

Christie needs 54.3 Square feet of laminate wood suppose each square foot of laminated wood cost $.60 find the amount she has to

Irina18 [472]

It will cost $33.

Since wood cost $ .60 sq ft, you can assume she needs to buy 55 sq ft because she will need to buy enough to have 54.3 square ft.

55 x $ .60 = $33

$32.58 would be he total for the 54.3 sq ft and .42 cents would be for the left over .7 sq ft that she didn’t use

Help!!!!!! show all work

Gnom [1K]

Hi There!

----------------------------------------------

Part A:

Slope Intercept Form: y = mx + b

m = slope (slope = $\frac{y2 - y1}{x2 - x1}$ )

b = y intercept

$m=\frac{4 - 6}{(-2)- (-6)} = \frac{-2}{4} = \frac{-1}{2}$

b = 3

Answer: y = -1/2x + 3

----------------------------------------------

Part B:

Just substitue f(x) for y.

Function Notation = f(x) -1/2 + 3

----------------------------------------------

Part C:

This function given looks almost the same but the slope is different while the one stated in the question has a slope of +2 and the equation given at the start with the slope being -1/2.

----------------------------------------------

Hope This Helps :)
