Algebra Help Please?....

Answer 1

A telephone company charges a fixed monthly rate plus a rate per minute of usage. The company charges $120 for 100 minutes of usage and $95 for 50 minutes of usage. An equation can be written to show the relationship between the total minutes used (x) and the total monthly charges (y). Which of the following best describes the steps to draw the graph of y against x?

Draw a graph which joins the points (100, 120) and (50, 95) and has a slope = 0.50
Draw a graph which joins the points (100, 120) and (50, 95) and has a slope = 2
Draw a graph which joins the points (120, 100) and (95, 50) and has a slope = 2
Draw a graph which joins the points (120, 100) and (95, 50) and has a slope = 0.50

Answer 3

the points to plot are (x,y)
for one of the points x = 50 and y = 95
the slope of the plot will be the difference in x values of the 2 points / difference in y values

Answer 4

ok

Answer 5

oops - sorry - the slope is the other way around ( silly me)
its difference in y values / difference in x values
