Apair of equations is shown below:
y = 7x − 9
y = 3x − 1
part a: in your own words, explain how you can solve the pair of equations graphically. write the slope and y-intercept for each equation that you will plot on the graph to solve the equations.
part b: what is the solution to the pair of equations?
i've tried doing it, but no matter what i keep getting the wrong answer

10 points? ? +++ me asap gabriella uses the current exchange rate to write the function, h(x), where x is the number of u. s. dollars and h(x) is the number of euros, the european union currency. she checks the rate and finds that h(100) = 7.5. which statement best describes what h(100) = 75 signifies? a) gabriella averages 7.5 u. s. dollars for every 100 euros. b) gabriella averages 100 u. s. dollars for every 25 euros. c) gabriella can exchange 75 u. s. dollars for 100 euros. d) gabriella can exchange 100 u. s. dollars for 75 euros.
