Answer:
the equation of the line is,
y = 2x - 1
Explanation:
let's take any two co-ordinates from the graph given,
x1, y1 = 2, 3
x2, y2 = -2, -5
the equation of the line is,
y = mx + b
where,
slope, m = y2 - y1 / x2 - x1
= -5 - 3 / -2 - 2
= -8/-4 = 2
let's take x1, y1 as x, y co-ordinate to find the constant b
3 = 2(2) + b
3 - 4 = b
b = -1
thus,
the equation of the line is,
y = 2x - 1
