Question

Determine the slope and intersection with the y-axis of each graph
y=-2x-1

Answer 1

slope = -2, Y intercept = -1

Explanation:

`y = mx + c`

`where \: m \: is \: the \: slope \: and \: c \: is \: the \: intercept`

So compare the equation with y= -2x-1

Therefore m = -2, c = -1

Answer 2

Explanation:

when x=2

y=2(2)-1

y=4-1
