Perpendicular to y=8 and contains the point (7,-2) in point-slope form, step by step.

x = 7

Step-by-step explanation:

y = 8 has a slope of 0.  A line perpendicular to that will have an undefined slope, so it will be x = a, where a is the x-intercept.

If (7,-2) is a point on the line, then the equation of the line must be x = 7.

Equation of the line in slope-intercept form is X = 7.

Step-by-step explanation:

Given Data:

Y = 8.

Points = (X1 , Y1) = (7, -2).

Step 1:  

If y = 8 it means that the slope value is 0.

Step 2:

We can also consider that the line is perpendicular and the slope is undefined which means that the equation of x cannot be found using the slope equation.

Step 3:

Therefore if the points on the line are (7, -2) then the equation of the line becomes x = 7.

the sum of all the angles in a triangle are equal to 180

so you can add   the 3 given angles together to equal 180:

5y + 2y + 2y = 180

or since all three angles have the same letter, combine the 3 angles to equal 180:

9y = 180

hi there!

the answer to this question is d: 35

step-by-step explanation:

5 to the power of 2 is 25

2 multiplied by 5 is 10

then you add the 2 numbers and you get 35
