Find the equation of the graph using the formula:
y=mx+c

y = 1x + 3

Step-by-step explanation:

Slope (m) =

Points: (0,3) & (-3,0)

m = 1

y = 1x + b

To find b:

3 = 1(0) + b

3 = b or b = 3

Final y = 1x + 3

Double Check:

3 = 1(0) + 3

3 = 3

0 = 1(-3) + 3

0 = - 3 + 3

0 = 0

Here, y = mx + c is the slope-intercept form of the equation of the line given in the graph, where m is the slope and the y-intercept is c. Here, the line cuts 3 on the y-axis and -3 on the x-axis. So, here the coordinates are (0,3) and (-3, 0) respectively.Firstly let us find the slope of the line m.So, m = 1And y-intercept c = 3So, the equation is like this:y = mx + cor, y = (1)x + 3or, y = x + 3

y = x + 3

Hope you could get an idea from here.

Cost of cooler alone = $ 7.47 Explanation: Method 1: Anton's bill including tax = $ 7.95 6 % of his bill accounts for sales tax. Sales tax = 6 100 × 7.95 ≈ $ 0.48 So cost of cooler alone = Total bill - tax = 7.95 − 0.48 = $ 7.47 Method 2: Anton's bill including tax = $ 7.95 , out of this 6 % is sales tax. This implies 94 % ( 100 − 6 ) of total bill accounts for cooler alone. Cost of cooler alone: = 94 100 × 7.95 = 0.94 × 7.95 = $ 7.47
