Question

What is the equation of the line, in general form, that passes through the point (1, 1) and has a y-intercept of 2

Answer 1

`The\ slope-intercept\ form:y=mx+b\\\\y-intercept\ is\ 2\ then\ y=mx+2\\\\The\ point\ (1;\ 1)\to substitute\ x=1\ and\ y=1:\\\\m\cdot1+2=1\\m+2=1\\m=1-2\\m=-1\\\\Finish:y=-1x+2\to y=-x+2\\\\General\ form:x+y-2=0`
