Number of Weeks
Which equation represents someone who saved more money per week than Matt but who had less money to start? Let x represent the
number of weeks, and let y represent the amount of savings.
OA y = 125x + 100
OC. y 175x+ 200
OB. y 160x + 250
OD. y=200x + 150

A linear function can be defined as a type of function whose equation is graphically represented by a straight line on the cartesian coordinate.

What is a graph?

A graph can be defined as a type of chart that's commonly used to graphically represent data on both the horizontal and vertical lines of a cartesian coordinate, which are the x-axis and y-axis.

How to calculate the slope of a line?

Mathematically, the slope of a straight line can be calculated by using this formula;

[tex]Slope, m = \frac{Change\;in\;y\;axis}{Change\;in\;x\;axis}\\\\Slope, m = \frac{y_2\;-\;y_1}{x_2\;-\;x_1}[/tex]

From the graph, the slope is given by:

Slope, m = (1800 - 200)/(10 - 0)

Slope, m = 1600/10

Slope, m = 160.

Note: The intercept (c) is equal to 250.

Mathematically, the standard form of the equation of a straight line is given by;

y = mx + c

y = 160x + 250.

In this context, we can infer and logically deduce that an equation which represents someone who saved more money per week than Matt but who had less money to start is y = 200x + 150.
