y = -1/10 + 2
Step-by-step explanation:
To get equation of line: y = mx + c
m = slope
We will use the two points to find the slope
slope formula:
![m\text{ = }(y_2-y_1)/(x_2-x_1)](https://img.qammunity.org/2023/formulas/mathematics/high-school/sukh4lu5s7fgiz5v423o6usjd9gul4kfrj.png)
![\begin{gathered} x_1=10,y_1=1,x_2=-10,y_2\text{ = }3 \\ m=(3-1)/(-10-10)=(2)/(-20)=(-2)/(20) \\ m\text{ = }-(1)/(10) \end{gathered}](https://img.qammunity.org/2023/formulas/mathematics/college/rskb6x075jx1y03nv19pz0hxkd2yj748en.png)
To get c, we need to use one of the points given:
Using point (10, 1) = (x, y)
1 = -1/10 (10) + c
1 = -1 + c
c = 1+1
c = 2
The linear equation becomes:
y = -1/10 + 2
