Answer:
Step-by-step explanation:
What is the equation of the line that passes through the point (2,−7)and has a slope of −4
Givens
<FOP = 2x + 2
<POQ = 10x - 8
<OF is bisects POQ
Comment
If you multiply POF (which is 2x + 2) by 2 it will be the same size as <POQ because POF is one of the bisected angles of < POQ.
Create an equation and solve
2(2x + 2) = 10x - 8 Remove the brackets.
4x + 4 = 10x - 8 Add 8 to both sides.
4x + 4 + 8 = 10x Combine like terms.
4x + 12 = 10x Subtract 4x from both sides.
12 = 10x - 4x
12 = 6x Divide by 6
x = 12/ 6
x = 2 <<<< answer A
Find <POF
< POF = 2x + 2
< POF = 2(2) + 2
<POF = 4 + 2
<POF = 6 <<<< answer B
Find <QOF
<QOF = <POF
<QOF = 6 <<<<< Answer C
Find <POQ
<POQ = 10x - 8
<POQ = 10(2) - 8
<POQ = 20 - 8
<POQ = 12 <<<<< Answer D
Answer:
it does not matter
Step-by-step explanation:
Because you still have to put both numbers but it still does not matter what goes first as long as it is on the graph it is alright to use whichever steps feel first but x is more commonly used before y
They should divided by 1 for the last step
