graph of a line passing through the ordered pair negative four comma negative four and the ordered pair six comma one
Your keyboard has keys on it specifically for typing numbers and commas, just so you know. (-4,-4) and (6,1)
There are a number of ways you can do this. I like slope intercept form, y=mx+b where m is the slope and b is the y-intercept. Find the slope first. Rise over run.
I know about the comma's i just copied and pasted this :L
Once you know m, pick a point you know (x,y), plug x, y, and m into y = mx + b, then solve for b to get the intercept. Use m and b to write the general form.
but please continue
Haha, gotcha. I'm just messing with you =) Try that out and ask me any questions that come up.
y = ½x - 2 is this it?
Great job =)
thanks
\[m = \frac{\text{rise}}{\text{run}} = \frac{1-(-4)}{6-(-4)} = \frac{5}{10} = \frac{1}{2}\] Now to find the value of b, I'll use the point (6,1) \[y = mx + b \rightarrow 1 = \frac{1}{2}*6 + b \rightarrow 1 = 3 + b\\ \rightarrow 1-3 = -2 =b\] So m = 1/2 and b = -2 gives y = (1/2)x -2
