Question 58365: Hi,
I can do this problem by sight; meaning I know what numbers will work by looking at it, I do not know how to do them if I couldn't do it by sight though.
The problem is:
x-2y=4
I did x=4 and y=0.
I know by looking at this that x could equal zero and y could equal a -4.
I do not know how to do the problem other than by figuring out in my head what 2 numbers would leave me with the answer of 4.
I hope you can help me. Thank you.

Question 58537: given these two points on a line, write the equation in slope-intercept form:
(5,-13) and (2,-1)
i did the coordinate approach and came out with: -1-(-13)/2-5=-4, which is the slope. to find the y=intercept, i took one of the points and did: 2=-4(-1)+b. I came out with 2=4+b. now subtracted 4 from both sides and got: 4-2=4+b-4 which simplifies to:-2=b. so my final equation would read: y=-4x+(-2). is this correct??
