Ответ:
y = -1/4x +2
Step-by-step explanation:
We know the y intercept is 2 ( where it crosses the y axis)
We also need to find the slope
( 0,2) and (4,1) are two points on the line
Using the slope formula
m = (y2-y1)/(x2-x1)
= (1-2)/(4-0)
-1/4
We can write the equation in slope intercept form
y = mx+b where m is the slope and b is the y intercept
y = -1/4x +2
