Question

Write an equation of the line that has a slope of 2 and contains the point (1, 1) in point-slope form.

Answer 1

Point-slope form: we need a point (x₀,y₀) and the slope "m".
y-y₀=m(x-x₀)

Data:
(1,1)
m=2

Therefore:
y-y₀=m(x-x₀)
y-1=2(x-1) This is the equation of the line in point-slope form.

Answer. y-1=2(x-1)
