Answer:
x-intercept: (-7.5 , 0) y-intercept: (0 , 5.5)
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.
Answer:
2x
Step-by-step explanation:
parallel lines are two lines that won't meet. the lines need to have the same slopes or else the will meet
