Answer:
C.
Step-by-step explanation:
I got this correct!
Answer:
A
Step-by-step explanation:
Slope-intercept form: y=mx+b
2x+3y = 12
3y = 12-2x
y = (12-2x)/3
y = 4-2/3x
Here we can see that the slope is -2/3 and y-intercept 4. We already got the answer so we dont need to try the other options.
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
