Will Mark The Brainliest. Write an equation of the line graphed in slope-intercept form using the variables x and y.
baherus [9]

Answer:

\boxed{y=-2x+5}

Step-by-step explanation:

The equation in slope-intercept form is given by:

y=mx+c

where m is the slope and c is the y-intercept.


The given line passes through so many points. We can use any two these points to find the slope of the line.

The line passes through (x_1,y_1)= (1,3) and (x_2,y_2)=(2,1).

The slope is given by;

m=\frac{y_2-y_1}{x_2-x_1}.


\Rightarrow m=\frac{1-3}{2-1}.


\Rightarrow m=\frac{-2}{1}=-2.

The y-intercept from the graph is c=5


Our equation finally becomes;

y=-2x+5
