1.For the first one on the horizontal line on the left put the dot on -4,3

Then right by the dot put +2/3x

For the second one, put the dot in the center and put +2x.

Reasoning for the second one. Since they are both on the y spectrum, we can do an algebra equation for it.

So, we would have 2x +2 - 2. This would give us 2x. The way we to get the center is because 0 is right there, and x is an unknown number so we can't place it anywhere. That is why we put +2x.

Line parallel to y-1=4(x+3) and passes through (4,32)

Lady_Fox [76]

Answer:

y - 32 = 4(x - 4)

Step-by-step explanation:

The equation of a line in point- slope form is

y - b = m(x - a)

where m is the slope and (a, b) a point on the line

y - 1 = 4(x + 3) ← is in point- slope form

with slope m = 4

Parallel lines have equal slopes.

Using m = 4 and (a, b) = (4, 32), then

y - 32 = 4(x - 4) ← equation of parallel line

What is the slope of (-6,8) and (-6,2)

SpyIntel [72]

Answer:

Undefined

Step-by-step explanation:

First, slope is change in y over change in x, or rise over run. Plugging these points in (y1-y2)/(x1-x2)=(2-8)/(-6--6), or -6/0. Oh no! You can't divide by 0. Therefore, the slope is undefined.

You can also see this by graphing the line, which is a straight vertical line. Vertical lines have undefined slopes.

OleMash [197]

Answer: see proof below

Step-by-step explanation:

Given: A + B + C = π and cos A = cos B · cos C

scratchwork:

A + B + C = π

A = π - (B + C)
