Question

if you have (1,-2) and (-3,1) how do you find the slope and y-intercept

Answer 1

The slope of the line through points (x1,y1) and (x2,y2) is given by :
\(\huge m=\frac{y_1-y_2}{x_1-x_2}\)
now,just put the values and find m.

Answer 2

i found the slope it is -3/4 and i put it into y-y1=m(x-x1) and i cant get the y -intercept

Answer 3

to get 'y' intercept from any equation, you just put x =0 in that equation :)

Answer 4

ok so the question on my worksheet says" explain how you would use the points (1,-2) and (-3,1) to graph a linear equation and find the slope and y-inercept

Answer 5

so you could graph it right ?
and y-intercept from graph is even easier, its where you line crosses x-axis

Answer 6

i mean crosses, y-axis

Answer 7

okay thanks.
