21g=84
g=84/21
g=4
The answer is B
Answer:
I know this is late but here
Slope = -1/25, y-intercept = 15
I can’t really explain it though
6*40= 240 + 6*2=12
240+12= 252
since the graph has direct variation as data in x axis increases y also increases.
so we need to find how many miles travelled per galloon .
we distance travelled per gallon =total distance travelled/galoons of fuel used.

for part b) slope=rise/run



slope of the graph is 2
Answer:
I think b, but I may be wrong
