Question

Write an equation of each line. Express your answer using either the general form or the slope–intercept form of the equation of a line, whichever you prefer.

Short answer

The equation of line is:$y=-x+1$.

Step-by-step solution

Step 1. Given information 

Graph of line is:

Step 2. Finding slope of the line. 

The two points on the line are: $(0,1)\mathrm{and}(1,0)$

Slope of the line is given by,

$$\begin{gathered} m=\frac{y_2-y_1}{x_2-x_1} \\ \Rightarrow m=\frac{0-1}{1-0} \\ \Rightarrow m=-1 \end{gathered}$$

Step 3. Finding y-intercept of the line. 

From the graph, y-intercept,$b=1$

Step 4. Finding equation of the line

Slope-intercept form of the line is: $y=mx+b$

Substituting slope and y-intercept in the equation above, we get,$y=-x+1$
