Answer: The value of y=9.
It does match-
The Y-Intercept is 12
And the slope is -3/1
You can confirm this by counting rise over run in the graph
Starting at the Y-Intercept (Y=12) the graph goes down 3 units (-3) over 1 unit (1)
This confirms that the slope is -3/1
Answer:
x=13
Step-by-step explanation:
Lines that are perpendicular to each other have opposite sign reciprocal slopes. The slope of the x-axis is 0, so the slope of the line will be undefined (vertical)
x = something
A vertical line has the same x-value all the way through, so the y-value will just keep going up.
Answer:
115 degrees is the third angle measure.
Step-by-step explanation:
All the angle measures of a triangle are supposed to add up to 180 degrees, so 180-65=115.
