Answer 16

try the slope-intercept form \[y=mx+b\]

Answer 17

\(b=0\) for both of them since they both start out at \((0,0)\).
So find the slope and replace \(m\) with that.

Hint: to find slope, use point-slope form...\[y_{2}-y_{1}=m(x_{2}-x_{1})\]

Answer 18

Point-slope form is used when you have two points (any points you pick off the same line), which are signified as:\[(x_{1},y_{1})\text{ and }(x_{2},y_{2})\]
