Im sorry, I yried to help, but I cant figure it out
Answer:
Answer is D.
Step-by-step explanation:
Which is not true?
So, lets assess the answers given to the question.
A. It is the equation of a horizontal line.
Yes, it is. Since there is only one y - value which is y = -4, we can confirm this is the y intercept, so therefore the x value is zero. But it's not the answer we're looking for.
B. It's slope is zero, yes the slope is zero. It only lists the y-intercept which confirms that the slope is 0.
C. Yes, I mean i can't really explain how. Just use desmos calculator, the graph is exactly perpendicular.
D. The line actually does cross the x-axis, -4 is the y intercept and the x value is 0, and zero is still a point. So D is the one which isn't correct making it the correct answer.
Those are adjacent angles. They will equal 180 degrees since they both ly on the same straight line. Straight line= 180 degrees.
10x-20+6x+8=180
Add 20 to both sides.
10x+6x+8= 200
Combine like terms.
16x=192
Divide both sides by 16.
x=12
I hope this helps!
