Y=2x because x axis is on the bottom and X axis always comes before Y axis!
Y=mx+b where m=slope which is change in y divided by change in x m=(-8-7)/(4-9)=-15/-5=3 so we have y=3x+b now we can use either point, I'll use (9,7), to solve for b or the y-intercept... 7=3(9)+b 7=27+b b=-20so our line is: y=3x-20
9 x 3 = 27
27/9=3
12 x 3= 36
36/3=12

In 1 hr the bus would have traveled 48.5 miles
To solve this, all you need to do is multiply 16 by 3/8. When you multiply a whole number by a fraction, make the whole number into a fraction by putting it over 1.
16 3
---- x ---- Multiply the numerators together and then the denominators.
1 8
(16 x 3) / (1 x 8)
48 / 8 Then divide.
