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 equation without 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? (Tmi)
