Question

is (-1, 5) a solution to the equation y = -x - -4?
yes no

Explanation:

Step1: Substitute x and y values

Substitute \( x = -1 \) and \( y = 5 \) into the equation \( y = -x - (-4) \). First, simplify the right - hand side. The equation \( y=-x - (-4) \) can be rewritten as \( y=-x + 4 \) (since subtracting a negative is like adding a positive).
Substitute \( x=-1 \): \( -(-1)+4=1 + 4=5 \).

Step2: Compare with y - value

The left - hand side \( y = 5 \) and the right - hand side after substitution is also 5. So when \( x=-1 \), \( y = 5 \) satisfies the equation.

Answer:

yes
