Given the points:
(8, 6)
(4, 2)
x1= 8
x2 = 4
y1 = 6
y2= 2
Write the equation in point-slope form:
Point-slope form:
y - y1 =m(x -x1)
Solution:
Before we can write in point-slope form, we must first find the slope of the line, we can find the slope by using the slope formula.
m = y2 -y1 /x2 -x1
m= (2 -6)/(4 - 8)
m = -4/-4
m= 1
Substitute the given values of x1, m and y1 to the formula for the point-slope form.
y - 6 = 1 ( x - 8 )
Final answer:
y - 6 = x - 8
