Answer:
y = (8/3)x - 3
Step-by-step explanation:
To get to slope intercept, just solve for y
3y - 8x = -9
3y = -9 + 8x
y = (-9 + 8x)/3
y = -9/3 + 8x/3 (distribute the 3 so we can reach the right form)
y = -3 + 8/3(x)
finally write in slope intercept form:
y = (8/3)x - 3
Answer:
The equation 4x -6y = 12 is in
"standard" form. if you modify it to be in the "slope intercept" (y=mx+b)
it will be modified to help more easily graph
y= 2/3 x -2 is the same equation in slope intercept (graphing) form...
here you can see that slope (rise over run) is positive and is 2/3 thus it goes from lower left to upper right... the "y-intercept" (the B) is at "-2" thus the line intercepts the y axis at -2
you can find the x and y intercepts by replacing the x with a 0 to get the y intercept, and then replacing the y with a 0 to get the x intercept

Time = distance/speed
Since you want to find the time Holly spent riding, you need to divide her distance (24 miles) by her speed (6 miles/hour) to get the number of hours (4) that she rode. Her starting time added to the time spend riding will give her ending time. One must subtract the riding time from the ending time to find the starting time.
Selection A is appropriate.
