Find the equation of the line shown
solniwko [45]

Answer:

y=-\frac{1}{4}x+2

Step-by-step explanation:

We will use the point slope formula: y=mx+b

We will start by finding the slope(m).
The formula for slope is

\frac{y_{2}-y_{1}}{x_{2}-x_{1}}

So if we just choose 2 random points on the line:

I choose (0,2) and (4,1), we get:

\frac{1-2}{4-0} = \frac{-1}{4}

That's our slope.

Next we need to find the y-intercept(b). We can find that by looking at the graph. It is where x=0. So in this case y=2 when x=0.

So in point-slope form the equation is:

y=-\frac{1}{4}x+2
