Hi ppl.

If Im given the coordinates below:

x: 32, 48, 64, 80, 96, 112

y: 6, 9, 12, 15, 18, 21

How do I find the slope and the y-intercept of the linear equationwithout using regression or any type of computer software (solve algebraically)?

slope: pick to random coordinates like (32, 6) and (112, 21) and then put it into y2 - y1 / x2 - x1?

y-intercept: well.. let x be 0 in the equation?? well I cant use regression? how do I get the equation?
