Answer:
D and F
Step-by-step explanation:
r: m=-2 y=1 y = -2x + 1
s: m=2 y=1 y = 2x + 1
t: m=1/2 y=1 y = 1/2x + 1
slope of r x slope of t = -2 x 1/2 = -1 (r and t is perpendicular)
all 3line have the same y intercept (0,1), they are not possible to be parallel
i can't tell you the answer, but i will teach you how to get it!!
first you convert it to a fraction, then you make it a decimal divide the top number by the bottom number, then you move the decimal two places to the right --> and add a percent symbol %
The answer would be 3 because 2 times 2 is 4 minus -1 would be 3
