Answer:
y = 4
Step-by-step explanation:
y - 1 = √y + 5
(y - 1)² = y + 5 (Square both sides)
y² - 2y + 1 = y + 5 (Expand left side)
y² - 3y - 4 = 0 (Subtract y and 5 from both sides)
(y + 1) (y - 4) = 0 (Factor)
y = -1, 4 (Use ZPP)
When we check y = -1 we see that it is not a solution so the answer is y = 4.

Answer:
The equation would be y = -1/2x + 4
Step-by-step explanation:
The formula for slope-intercept form is y = mx + b, where m is the slope and b is the intercept. So, you simply add those numbers in where those letter are.
