Answer:
y = -2/5x + 1
Explanation:
the x,y co - ordinates given in the graph are,
x1, y1 = 5, -1
x2, y2 = -5, 3
the equation of the line is, y = mx + c
where c, constant is the y - intercept i.e. the point on the graph where the line touches the y - axis
and as per the graph c = 1
slope, m = y2 - y1 / x2 - x1
= 3 + 1 / -5 - 5
= 4 / -10
= -2/5
thus, the equation of the line is,
y = -2/5x + 1
