Hopefully this helps :D
Slope-intercept form is:

Where 'm' is the slope and 'b' is the y-intercept.
Only the first equation is in slope-intercept form, so that crosses out the first and last options. It also crosses out the second option since the first equation is already in slope-intercept form.
For the third option, let's convert the second equation into slope-intercept and see for ourselves:

Subtract 'x' to both sides:

Divide 3 to both sides:
So option C is correct.
Let the bigger no. = x+48
smaller no. = x
5x = x + 56
4x = 56
x = 14
x + 48 = 62
Check :
62-14= 48
5×14= 70 is equal to 62+8=70
Ans : 14 and 62
This is how I do it. 330÷5=66. Now for every gallon we have 66 miles. Now divide 450 by 66 to see how many gallons we need. 450÷66=6.81818181818 which rounds to 6.8. The car will need 6.8 gallons of gas to go 450 miles
