A pair of equations is shown below:
y = 2x − 1
y = 4x − 5
Part A: In your own words, explain how you can solve the pair of equations graphically. Write the slope and yintercept for each equation that you will plot on the graph to solve the equations. (6 points)
Part B: What is the solution to the pair of equations? (4 points)

Best ResponseYou've already chosen the best response.0That's a very rough sketch. But the idea is to graph both of the equations, and find where they intersect. That point of intersection is a solution to both equations.

Best ResponseYou've already chosen the best response.0Okay so. Let's just start with one of the equations. y = 2x  1. Can you graph that equation for me, by itself?

Best ResponseYou've already chosen the best response.0sure. so we are solving a pair of equations using the graphing method. What you need to do is to graph each equation separately on the same sheet of paper . letting x be any value so you can find out what y is. The answer is when both equations share the same point.

Best ResponseYou've already chosen the best response.0So Christian that's good you know m and b. And now the next step is to visualize them geometrically. So could you plot the graph for me, of y = 2x  1?

Best ResponseYou've already chosen the best response.0let x be any value from x =0 to x = 3 and we plug it into the y =2x1 to figure out what our y is.. then we have a point . Fore example, when x = 0, y =1 so our coordinate point is (0,1)

Best ResponseYou've already chosen the best response.0no no no for y = 4x5. let x = 0,1,2,3...... find the y values and plot them.. sorry I am freezing bad again with OS

Best ResponseYou've already chosen the best response.0Christians that's fine, but to understand it so you can write it in words, you should do as UsukiDoll is suggesting, and graph it first. Once you do that and can see what's happening, it will be very easy to explain it in words.
