write the equation (2,5) and (-3,-4)
is an emergency
Calculate the slope, m.
m = (y2, - y1) / (x2 - x1)
m = (-4 - 5) / (-3 - 2)
m = -9 / -5
m = 9/5
Calculate the y-intercept, using one of the points. (2,5)
y = mx + b
y - mx = b
b = 5 - 9/5(2)
b = 5 - 18/5
b = 5 - 3 3/5
b = 5 - 3.6
b = 1.4
The equation y = mx + b is now: y = 9/5 x + 1.4
