The phone which Jayden should choose include: C. The By-Phone 15+ will cost $1,279 after one year so it is the best deal.

In Mathematics and Geometry, the slope-intercept form of the equation of a straight line is given by this mathematical equation;

y = mx + b

Where:

  • m is the slope or rate of change.
  • x and y are the points.
  • b is the y-intercept or initial value.

Based on the information provided above, a linear equation that models the By-Phone 15+ can be written as follows;

y = mx + b

y = 40x + 799

A linear equation that models the Cyborg Galaxy can be written as follows;

y = 65x + 585

When x is 1 year or 12 months, the total cost is given by;

y = 40(12) + 799

y = $1279 ⇒ By-Phone 15+

y = 65(12) + 585

y = $1365 ⇒ Cyborg Galaxy

In conclusion, Jayden should choose the By-Phone 15+ because it will cost $1,279 after one year, so it is the best deal.
