passes through(1,9),slope=2

Question

Please help

Answer 1

I imagine you want the equation of a line that passes through the point (1,9) and has a slope of 2.

That means you should use the Point-Slope form of the equation of a line.

y - y₁ = m(x - x₁)

y - 9 = 2(x - 1)

y - 9 = 2x - 2

y = 2x + 7
