First of all, subtract the amount the boots costed from the total price.
109.95-29.99
= 79.96
Now you have the price of the 4 sandals.
To find the price of 1 pair, divide this total by 4
79.96 / 4
= 19.99 $ for one pair of sandals!
The slope and the y intercept of the line on the graph is -1/4 and 1.
<h3>What is a Straight Line Function ?</h3>
A straight line function is what can be written in the form of
y =mx +c
where m is the slope and c is the intercept on y axis.
The intercept on the y axis , c = 1
at x = 4 , y=0
and at x = 0, y =1
The slope can be calculated as
y = mx+1
0 = 4m +1
m = -1/4
Therefore the slope and the y intercept of the line on the graph is -1/4 and 1.

If you want to solve that put it in the formula to find the slope
M=
Y1-y2
---------
X1-x2
And plug that into slope int form with one of the points to find the y int/ b value and then your have ur equ
