Question

slope 2; y-intercept (0, -3)

Answer 1

need help, please

Answer 2

1) Write general equation for lines:
y = mx + n (m is slope)

2) Put slope = 2
y = 2x + n

3) Put the values of the point you have (x,y) = (0, -3)
-3 = 2*0 + n
n = -5

4) Write first equation and put values of m and n into the equation
y = 2x -5

Answer 3

how does n=-5

Answer 4

Sorry :D
n = -3
y = 2x-3
