Question

Original Equation: y = x + 2 The graph of the original equation is shown. Which equation will change the slope for the graph of the original equation to -1? A) y = x - 1 B) y = -x + 2 C) y = -x - 1 D) y = -x - 2

Answer 1

b

Explanation:

Answer 2

B. y = -x + 2

Explanation:

Now, the standard slope formula is y = mx + b, where m is the slope and b is the y intersect. From the graph pictured, we know that it has a slope of 1 since it goes up one point and to the right one point. So, I know the equation of this line is y = x + 2. Now, all that is left is to find this equation with a -x, which indicates that it is a -1 slope. Since option B has the formula y = -x + 2, that is the correct answer.
