3/6+10/6=13/6
-23/3=13/6a
(-23/3)/(13/6)=a
a=-46/13
Answer:
Equation: y + 1 = -2(x - 0) OR y + 3 = -2(x - 1)
Slope: -2
Y-intercept: (0, -1)
Step-by-step explanation:
First, create an equation in point-slope form using ONE point. Using (0,-1):
y - y1 = m(x - x1)
y + 1 = m(x - 0)
Then, use both points to find slope:
![\frac{y2-y1}{x2-x1} =m](https://tex.z-dn.net/?f=%5Cfrac%7By2-y1%7D%7Bx2-x1%7D%20%3Dm)
![\frac{-1-(-3)}{0-1}](https://tex.z-dn.net/?f=%5Cfrac%7B-1-%28-3%29%7D%7B0-1%7D)
![\frac{2}{-1}=m=-2](https://tex.z-dn.net/?f=%5Cfrac%7B2%7D%7B-1%7D%3Dm%3D-2)
Then, plug the slope into the equation and rewrite in the form of y=mx+b:
y + 1 = (-2)(x - 0)
y + 1 = -2x
y = -2x - 1
-1 = b OR (0, -1)
Final answers:
Equation: y + 1 = -2(x - 0) OR y + 3 = -2(x - 1)
Slope: -2
Y-intercept: (0, -1)
