4.2 Solve 5g+3p-117 = 0
Tiger recognizes that we have here an equation of a straight line. Such an equation is usually written y=mx+b ("y=mx+c" in the UK).
"y=mx+b" is the formula of a straight line drawn on Cartesian coordinate system in which "y" is the vertical axis and "x" the horizontal axis.
In this formula :
y tells us how far up the line goes x tells us how far along m is the Slope or Gradient i.e. how steep the line is b is the Y-intercept i.e. where the line crosses the Y axis
The X and Y intercepts and the Slope are called the line properties. We shall now graph the line 5g+3p-117 = 0 and calculate its properties
Graph of a Straight Line :
Calculate the Y-Intercept :
Notice that when g = 0 the value of p is 39/1 so this line "cuts" the p axis at p=39.00000
p-intercept = 117/3 = 39 Calculate the X-Intercept :
When p = 0 the value of g is 117/5 Our line therefore "cuts" the g axis at g=23.40000
g-intercept = 117/5 = 23.40000 Calculate the Slope :
Slope is defined as the change in p divided by the change in g. We note that for g=0, the value of p is 39.000 and for g=2.000, the value of p is 35.667. So, for a change of 2.000 in g (The change in g is sometimes referred to as "RUN") we get a change of 35.667 - 39.000 = -3.333 in p. (The change in p is sometimes referred to as "RISE" and the Slope is m = RISE / RUN)
Slope = -3.333/2.000 = -1.667 Geometric figure: Straight Line
Using the data below, what is the equation for the line of best fit? Remember, put your answer in y = ax + b form and round any decimals to two places.
Begin by subtracting 35% from 100%, giving 65% which is equivalent to 0.65 Then multiply 147 * 0.67 = 98.49 Now for a sales tax you would want to multiply by 108.5% (or 1.085) as you are paying the previous price and them some 98.49 * 1.085 = <span>106.86165 You can round to the second decimal place since you can't have a monetary value less than a penny your answer would be $106.86 </span>
