Answer:x equals 4
Step-by-step explanation:
Answer:
Correct answer is A 357,5
Step-by-step explanation:
Look carefully at the first pair: (−3, 9), (−3, −5) Note that x does not change, tho' y does. This is how we recognize a vertical line (whose slope is undefined). The equation of this vertical line is x = -3.
Looking at the second pair: from (3,4) to (5,6), x increases by 2 and y by 2; thus, the slope is m = rise/run = 2/2 = 1.
Third pair: as was the case with the first pair, x does not change here, and thus the equation of this (vertical) line is x=0 (which is the y-axis). The slope is undefined.
It has to be 5 because 2.5 is half so the other half 2.5 .so 2.5 +2.5 =5
