Answer:
3) y = 3x
Step-by-step explanation:
a line equation is typically written as
y = ax + b
a is the slope, the inclination of the line. it is defined as ratio of "y coordinate change / x coordinate change" when going from one point to another on the line.
so, e.g. going from (0,0) to (4,12) means
x changes by +4 (from 0 to 4)
y changes by +12 (from 0 to 12)
so, the slope is +12/+4 = 3
and the line equation starts like this
y = 3x + b
now, b is the y-intercept : the y value, where the line intercepts (crosses) the y-axis. in other words, the y value where x = 0.
and we have that right away, as the line goes through (0,0). that IS the y-intercept point. the y value there is 0.
therefore, b=0.
and so the full line equation is
y = 3x
A. You are told that the length equals (x + 15), which means that you must factorise the area in order to find the width:
45 ÷ 15 = 3
(x + 15)(x + 3)
So the width is x + 3
b. Now you substitute in the value of x into both brackets, so
length: (x + 15) = (8 + 15) = 23 yards
width: (x + 3) = (8 + 3) = 11 yards

Hello there!
Pearl drives 18 Miles with every 1 gallons of gas, Lourdes Drives 24 miles every 1 gallons of gas. Lourdes is using less gas and driving more miles than Pearl every gallon so he is using gas more efficiently.
Hope this helped!!
