Explain? Write an equation that describes the line passing through (4, -2) with a slope of 1/2? So I know that I have to put it into point slope form to get it into the slope intercept form, but how do you do that when you have fractions in it?

Same as you would with any other numbers

plug everything in, what do you have?

anonymous · Answer

So if you get y - ( - 2) = 1/2 (x - 4) how do you distribute the 1/2?

anonymous · Answer

like normal.  1/2 * x is (1/2)x   

what is 1/2 * -4?

anonymous · Answer

- 1?

anonymous · Answer

I meant - 2

anonymous · Answer

Yep

so we have

y+2=(1/2)x-2

now subtract 2 from both sides

anonymous · Answer

Okay so y + 2 -2 = (1/2)x - 2 - 2 = y = (1/2)x - 4?

anonymous · Answer

Yep :)
