Answer:
y = -x + 4
Step-by-step explanation:
Mathematically, the equation of a straight line is;
y = mx + b
where m is the slope and b is the y-intercept
from the plot, the y intercept is 4
So we have;
y = mx + 4
To get the value of m, we substitute the coordinates of any point and solve for m
we select the point; (4,0)
so;
0 = m(4) + 4
4m = 0-4
4m = -4
m = -1
so the equation of the line is;
y = -x + 4
