Answer:
1) y = 200x + 120
2) - 200x + y = 120
Step-by-step explanation:
Equation of the line
The equation of the line in standard form is:
Ax + By = C
Where A, B, and C are constants.
The equation of the line in slope-intercept form is:
y = mx + b
Being m the slope and b the y-intercept.
1)
Each shirt costs 200 pesos. Let's assume Jacob purchases x shirts. The cost of the shirts alone is 200x.
Assuming the shipping cost is 120 regardless of the purchased shirts, then the total cost is:
y = 200x + 120
This is the slope-intercept form of the line.
2) Rearranging the above equation:
- 200x + y = 120
It's the standard form of the line
