Question

Does the point (2, –1) satisfy the equation y = x + –3?

Answer 1

Yes it does satisfy the equation

Substituting x=2 and y=-1 into the equation we get:

-1=2-3

-1=-1

Answer 2

yes the given point satisfies the equation

Explanation:

point (x, y) = (2, -1)

equation is:

y = x - 3

by substituting the values:
