Answer: $15
Step-by-step explanation:
The normal price of the mirror is unknown we do not know that yet. So, let y represent the unknown number. The discount is 20 percent, we turn 20 into a decimal which would be 0.2. The amount of discount is $3. So, 0.2y equals to $3.
Then we divided.
y = 3 ÷ 0.2
And when you divide that is would be 15.
So, the regular price of the mirror is $15.
Answer:
substitute y = mx +b = (2/3)x -2
Step-by-step explanation:
slope intercert form looks like this
y = mx + b
m is the slope
b is the y intercept
The line intercepts the y at -2
To find slope, pick 2 points to find the slope
m = (y2 - y1)/(x2-x1)
i select point 1 (0,-2) and point 2 (3,0)
m = (0-(-2))/(3-0) = (2)/3
substitute y = mx +b = (2/3)x -2
