Question 34799: Determine the equation fo each line. Write the answer in standard form using only intergers as the coefficients.
The Line through (-2,0) iwth slope -3/4.
I tried.
Y=mx+b
Y=-3/4+-2/0

it never ceases to amaze me how students fail to understand something and THEN proceed to do more convoluted work than is actually necessary.

y = mx + c is a form of a straight line where m is the gradient and c is the y-intercept. We are given the value of m (-3/4) and also x (=-2) and y(=0), to find c.

y = mx+c
+y+=+%28-3%2F4%29x+%2B+c+
+0+=+%28-3%2F4%29%28-2%29+%2B+c+
+0+=+%286%2F4%29+%2B+c+
+c+=+-6%2F4+

--> so the equation of this line is +y+=+%28-3%2F4%29x+-+%286%2F4%29+. Now the question doesn't want it in this form. It wants no fractions first, so we re-write it as +4y+=+-3x+-+6+.

It also says "standard form" which means no negatives, so again re-arrange it:
+4y+=+-3x+-+6+
+4y+%2B+3x+%2B+6+=+0+
