graph and write solution number 1 4x+6y=12 and 2x-4y=20 number 2 is 2x-4y=8 and 6x-4y=-24 number 3 is y=2x-3 and y=2x+1

Question

This is due today i have to hurry up and i have to graph and solve those 

Answer 1

We're not supposed to DO your homework for you, Alex; just help you.

 

4x+6y = 12

2x-4y=20

 

Convert to slope-intercept form (y = mx + b):

 

y = (-2/3)x + 2       y-intercept = 2, slope = -2/3

y = (1/2)x - 5         y-intercept = -5, slope = 1/2

 

Graph them using the y-intercept and slope.  The point where the two lines cross is the solution.  Use the same method for numbers 2 and 3.  On #3, remember that if two lines have the same slope, they are parallel and do not cross.
