Answer:

See below.

Explanation:

First, from the graph, we can already pick out two points: (0,2) and (4,0). Note that (0,2) is the y-intercept.

Therefore, we can use slope-intercept form or
y=mx+b where m is the slope and b is the y-intercept.

We already know the b, so:


y=mx+2

Now, we can plug in the ordered pair (4,0) to help us determine the slope (or you can just use the slope formula for the two ordered pairs):


0=m(4)+2


-2=4m


m=-1/2

Thus, the entire equation is:


y=-(1)/(2) x+2

Answer:

y = -1/2x+2

Explanation:

Two points on the line are (0,2) and (4,0)

We can find the slope

m = (y2-y1)/(x2-x1)

= (0-2)/(4 -0)

= -2/4

- 1/2

We know the y intercept is 2 since it crosses the y axis at 2

The slope intercept form is

y = mx+b where m is the slope and b is the y intercept

y = -1/2x+2
