Help? Step by step..

Give the slope and the y intercept of the line -2x-4y=5.

Answer 1

rearrange into y = ax + b
-2x - 4y = 5
- 4y = 2x + 5
y = -2/4x -5/4
y = -1/2x - 5/4
the gradient/slope is the coefficient of x
and the y-intercept can be calculated when x = 0 or u can see it is the last term.
y = -1/2(0) - 5/4
y = -5/4
