Question 212783
GRAPH THE EQUATION y = 1/2x + 3/2
2) y = x + 2
x + 2y = 16 x= __________ y=_______
3) 2x = 5y - 3
6x - 15y = -3
4) 5X - 2Y = 36
3X + 4Y = 6

Since I didn't understand what you wrote, I answered some of the problems as best as I can in what you meant.


Step 1.  Just a quick note.  When you have an equation just plot two points x=0 and find y using the equation and x=0 and find x using the equation.   Then draw a line between two point. 

Graph  y = 1/2x + 3/2

Step 2.  The following will solve  y = x + 2


x + 2y = 16 x= __________ y=_______.  Rewrite y=x+2 as -x+y=2

Step 3.  The following will solve  3) 2x = 5y - 3, 6x - 15y = -3


*[invoke linear_substitution "x", "y",-2,5,3,6,-15,-3 ]


Step 4.  The following will solve 5X - 2Y = 36,  3X + 4Y = 6


*[invoke linear_substitution "x", "y", 5, -2, 36, 3, 4, 6 ]



I hope the above steps were helpful. 

 
And good luck in your studies!
