Question 50652: Dear Tutor,
Please help me with this problem..thanks!
Why is 2y+7x=-3 considered a line? We were asked in multiple choice form, and I figured this equation was a line by process of elimination but I would like to know why.
Thank You,

Any equation that is in the form of a number times x plus or minus a number times y equal to a number term will ALWAYS be a straight line. This form Ax+By=C is called the standard form of a line.

Also, any equation in the form of y = mx + b (called the slope-intercept form of a line) is also a straight line.

It's when you get x^2 or y^2 or division by x or y, like y = 12/x, etc. Then this is NOT a straight line.
