The only type of line with undefined slope is a vertical line.
In a vertical line, all points have the same x-coordinate.
The general equation of a vertical line is x = k, where k is the x-coordinate of all points on the line. If you are given one point, then you know the x-coordinate of that point, but since all points have the same x-coordinate, you also know the x-coordinate of all points.
Equation is: x = -6

Same explanation as above.
x = 2
Answer:
1 / 216
Step-by-step explanation:
Remember, when you divide fractions you have to multiply by the reciprocal
1/6 ÷ 6/1 ÷ 6/1
1st step: 1/6 ÷ 6/1 = 1/6 · 1/6 = 1/36
2nd step: 1/36 ÷ 6/1 = 1/36 · 1/6 = 1 /216
Answer:

Step-by-step explanation:
Using the product to sum formula
sinxcosy =
[ sin(x + y) + sin(x - y) ] , then
2sinxcosy = sin(x + y) + sin(x - y)
Given
2sin75°cos15° ← with x = 75 and y = 15 , then
= sin(75 + 15) + sin(75 - 15)
= sin90° + sin60°
= 1 + 
= 
Answer:
Isaac has $4.80 left
Step-by-step explanation:
$1.20 + 2.00 = 3.20
$8.00 - 3.20 = 4.80
