Question

Complete the equations of the system in slope intercept form use a decimal for the slope if nessisary

Line 1 line 2
X y. X y
0 3. -1 1
1. 5. -2-1
Line 1:y=____x+____
Line 2:y=____x+____

Answer 1

`m=(y_1-y_2)/(x_1-x_2)`

Line 1:

`m=(5-3)/(1-0)\\ m=(2)/(1)\\ m=2\\\\ \hbox{Point (0,3) is y-intercept so } b=3\\\\ y=2x+3`

Line 2:

`m=(1-(-1))/(-1-(-2))\\ m=(2)/(1)\\ m=2\\\\ 1=2\cdot(-1)+b\\ 1=-2+b\\ b=3\\\\ y=2x+3`
