Because you have two variables and only one equation, you can only solve for approximate answers, and not complete, absolute answers.
<h3><u>You can simplify this equation to x = -4y + 12</u></h3>
y - 3 = -1/4(x + 3)
Distributive property.
y - 3 = -1/4x - 3/4
Multiply all terms by 4.
4y - 12 = -x
Multiply all terms by -1
-4y + 12 = x
Answer: k < 3.5
explanation: < means less than and > means more than and = means equal to so k < (less than) 3.5
Well, to get the x intercept you have to substitute 0 for y and solve for x, and get rid of the parenthesis ( y=2x+3*x-1*x-4 ) unless you want three different x-intercepts. So if you do want those three intercepts, leave the parenthesis.
