The equation which best represents the graph shows the amount of money that Janice saves each week from her summer job is option A which is y=200x.
Given a graph showing the amount of money that Janice saves each week from her summer job.
Equation is relationship between two or more variables expressed in equal to form. Equation of two variables look like ax+by=c. It may be linear equation, quadratic equation and cubic equation.
Equation can be formed from any two points present on the graph with the help of following formula:
[tex](y-y_{1})=(y_{2} -y_{1} ) /(x_{2} -x_{1} )*(x-x_{1} )[/tex] where [tex](x_{1} ,y_{1} ),(x_{2} ,y_{2} )[/tex]are the points.
So,we have to find points first which are (6,1200),(7,1400)
Put the values in the formula:
(y-1200)=(1400-1200)/(7-1)*(x-1200)
y-1200=200/1(x-6)
y-1200=200(x-6)
y-1200=200x-1200
y=200x-1200+1200
y=200x
Hence the equation shows the amount of monet that Janice saves each week from her summer job is option A which is y=200x.
