A pair of equations is shown below:

y = 6x − 4
y = 5x − 3

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. (6 points)

Part B: What is the solution to the pair of equations? (4 points)

if you are trying to solve it graphically you first plot the y-intercept point (-4) in the first one and -3 in the second this is because a straight line is defined by y = mx + b where b is the y-intercept and m is the slope/gradient. The y intercept simply is the point on the graph where the x value is zero and the point falls somewhere on the y axis.  After you plot that point you use the slope which is rise over run to plot the second point. for the first one its 6/1 which means from (0,-4) you would move up 1 and over 6 yielding (6,-3) plot the next point and then draw a straight line. Do the same thing for the second line and draw a straight line through the points. Where the two lines cross that point set is the solution for the the equations.

So if they want you to do it graphically, here's what you do: https://www.desmos.com/calculator

on the left side theres a space to put in equations, just type in 6x - 4 and then in a separate box 5x - 3

anonymous · Answer

this will show you where they intersect and give you the coordinates

i dont understand it :( wat should i put

Alright here let me show you

So on the right there it lets you enter almost anything. Once you go up through math classes you will get more complicated equations and functions, but this site lets you put any of them in there. And that little gray point where they meet is the answer (1,2)

oh okay

anonymous · Answer

So the answer to the first question would be:
Graph the two functions and see where they intersect
Second question: (1,2)

anonymous · Answer

Oh, and slope ok, slope of 6x - 4 is 6, 5x - 3 has a slope of 5

anonymous · Answer

Y-intercept of 6x - 4 is -4, y-intercept of 5x - 3 is -3
