How would I solve this -3x+4y=8 what steps would I take to solve this and graph it?
Solution
-3x+4y=8
 
 To convert this into a graphing equation, we must use the format of...
 y=mx+b
 m=slope
 b=y-intercept
 
 -3x+4y=8
 Let\'s isolate y.
 We will begin by adding 3x to both sides...
 3x-3x+4y=8+3x
 4y=8+3x
 or
 4y=3x+8
 We will now divide both sides by four...
 (4y)/4=((3x)/4)+8/4
 Simplify...
 y=((3/4)(x))+2
 
 The slope of the line is 3/4...
 Slope= (y2-y1)/(x2-x1)
 This means that as the y-coordinators change by 3 units, the x=coordinates change by 4.
 Let\'s plug in a few numbers...
 x=4-------y=((3/4)(4))+2=3+2=5
 x=8-------y=((3/4)(8))+2=6+2=8
 x=12----y=((3/4)(12))+2=9+2=11
 
 The y-intercept is the position of y when x=0...
 y=(3/4x)+2
 y=((3/4)(0))+2
 y=2
 
 (0,2) is the y-intercept.
