I’m confused on how to find the equation...(help ASAP) thxxxxx

Answers

Answer:

Step-by-step explanation:

Remark

You can use the two points marked to find the slope. One of them is the y intercept which you need to get the equation.

(0,4) is one of the points.  This is the y intercept.

(8,0) is the other point you can use

Slope

m = (y2 - y1)/(x2 - x1)

Givens

y2 = 4

y1 = 0

x2 = 0

x1 = 8

Solution

m = (4 - 0) / (0 - 8)

m = 4/-8

m = - 1/2

y_intercept = 4

Equation

y = -1/2 x + 4

In order for two equations to be parallel they have to have the same slope

The only answer with equation that have the same slope is b

They both have a slope of 2

Hope this helps :)

Answer:

B.

Step-by-step explanation:

If two lines are parallel, that means that their slopes are the same.

If they're perpendicular, their slopes would be the negative reciprocal of the other.

For example, if line 1's slope was 5 and line 2 was parallel to it, that means that line 2's slope must be 5 as well. If line 3 was perpendicular to line 1, that meant that line 3's slope would be -1/5.

Which of the following statements are true? Select all that apply.
(Y=136)

Answers

Answer:

B. x + y = 180° and C. y = z

x = 180° - 82° - 54°

x = 64°

x + y = 180°

64° + 136° = 180°

so, x + y = 180° it's should be correct

∠y°,∠z° are vertical opposite angles.
