Question

Can you guys find the slope and y-intercept

Answer 1

Explanation:

Plot any tow points on the line and find the slope

(-1 , 3) ; ( -2 , 1)

Slope =
`(y_(2)-y_(1))/(x_(2)-x_(1))`

`= (1-3)/(-2-[-1])\\\\= (-2)/(-2+1)\\\\=(-2)/(-1)\\\\=2`

m = 2 ; (-1 , 3)

y - y1 = m(x - x1)

y - 3 = 2*(x - [-1])

y - 3 = 2*(x + 1)

y -3 = 2*x + 2*1

y -3 = 2x + 2

y = 2x + 2 + 3

y = 2x + 5

Slope = 2

y-intercept = 5
