Answer:
equation of the line is:
y = 1/2x - 7.6
Explanation:
the given co - ordinates are:
x1, y1 = 3.2, -6
x2, y2 = 5.2, -5
standard form for the equation of the line is:
y = mx + c
where:
slope, m = y2 - y1 / x2 - x1
= -5 + 6 / 5.2 - 3.2
= 1/2
let's take x1, y1 as x, y co - ordinate to find the value of constant, c:
-6 = 1/2(3.2) + c
-6 - 3.2/2 = c
c = -12 - 3.2 / 2 = -15.2/2 = -7.6
thus,
equation of the line is:
y = 1/2x - 7.6
