Question

is (-3, 1) a solution to the equation $y = -2x - -1$? yes no

Explanation:

Step1: Substitute x and y values

Given the point \((-3, 1)\), so \(x = -3\) and \(y = 1\). Substitute into the equation \(y=-2x - (-1)\).
First, simplify the right - hand side: \(y=-2x + 1\) (because subtracting a negative is adding a positive, so \(-(-1)=1\)).
Now substitute \(x=-3\) into \(-2x + 1\): \(-2\times(-3)+1\)

Step2: Calculate the right - hand side

Calculate \(-2\times(-3)=6\) (because the product of two negative numbers is positive). Then \(6 + 1=7\)
The left - hand side \(y = 1\), and the right - hand side is \(7\). Since \(1
eq7\), the point \((-3,1)\) is not a solution to the equation.

Answer:

no
