Answer:
y=-[tex]\frac{6}{5}[/tex]x+2[tex]\frac{1}{5}[/tex]
Step-by-step explanation:
We have to find the slope first. to do this, we need to use point slope formula: [tex]\frac{y_{2}-y_{1}}{x_{2}-x_{1}}[/tex]. Plug in the numbers, and we get [tex]\frac{-5-1}{7-1}[/tex], or -[tex]\frac{6}{5}[/tex].
Now we have the equation y=-6/5x+b. To find b, we can plug in any coordinate and solve. Let's use (1,1).
1=-6/5(1)+b
1=-6/5+b
b=2[tex]\frac{1}{5}[/tex]
So, added all together our equation is y=-[tex]\frac{6}{5}[/tex]x+2[tex]\frac{1}{5}[/tex]
