A line passes through the two points P(5,5) and Q (-1,-1). Write the equation in slope-intercept form

Solution

(x1,y1)=(5 ,5 ),(x2,y2)=( -1, -1),

slope m=[(y₂-y₁)/(x₂-x₁)]

slope m=[(-1-5)/(-1-5)]

m=1

equation of line in point slope form is y-y₁=m*(x-x₁)

y -5 =1(x-5)

y -5 =x-5

y =x is the equation of line in slope intercept form
