Explanation:
4x - y = 5
You need to convert this equation to point intercept form: y = mx + b where m = slope and b = y-intercept.
4x - y = 5
subtract 4x from both sides:
4x - y - 4x = 5 - 4x
-y = 5 - 4x
divide both sides by -1:
(-y)/-1 = (5 - 4x)/-1
y = -5 + 4x
rearrange right side:
y = 4x - 5
Remembering that: y = mx + b where m = slope and b = y-intercept
slope = 4
y-intercept = -5 or (0 , -5)
