Example. Convert y=54x+5 y = 5 4 x + 5 , graphed on the right, to standard form. The only fraction is $$ \frac { 5}{ \red 4} $$ so you can multiply everything by 4. Solve for the y-intercept (or "b" in the slope interceptequation) which is 20 in this example.
Solution :
1st -
2nd -
3rd -
4th -
Conclusion - only third choice has negative equivalent value
3(x+2)=7 X=1/3 Because 3(x+2) would simplify to 3x+6=7 and then its a two-step equation
Distance=amount of gas times miles per gallon
distance=y
amount of gas=x
mpg=?
given
y=300
x=10
300=10 times ?
divide both sidesj by 10
30=?
equation is
y=x times 30 or
y=30x
