Answer:
1. Not proportional 2. is proportional. For 3, 4, 5, and 6 just plot them.
Step-by-step explanation:
For 1, y intercept/x intercept is not 0 when you graph, thus not proportional. Number 2 is, thus proportional. For 3, 4, 5, and 6 you would plot them accordingly. So for (-5, -2) Start as 0,0 and go 5 to the left as it's negative, and 2 down as it is also negative. Do the same for others.
Answer:
a 1.6 miles
Step-by-step explanation:
1/8 hour=7.5
60/7.5=8
1/5*8=1.6
Answer:
x = -1
Step-by-step explanation:
1/2 (3x +4 ) = 1/2
1/2 x 3x + 1/2 x 4 = 1/2
1.5 x + 2 = 1/2
1.5x = 1/2 -2
1.5x = -1.5
1.5x /1.5 = -1.5/1.5
x = -1
Check Back
1/2 ( 3 x -1 + 4) =1/2
1/2 ( 1) =1/2
1/2 =1/2
Is that all the question says ??
Given that they follow the format for straight lines and are therefore straight lines, they would only intersect once and that would be at (0,1) where they both have a y intersect.
Hope this helps :)
