Question

If (-1, y) lies on the graph of y = 22x, then y=
A.4
B.1/4
C.1
D.1/5

Answer 1

If
`\((-1, y)\)` lies on the graph of
`\(y = 22x\), then \(y = -22\)` (Option A).

Step-by-step explanation:

Substituting
`\(x = -1\)` into the equation
`\(y = 22x\)` , we get
`\(y = 22 * (-1) = -22\).` Therefore, when
`\((-1, y)\)` lies on the graph,
`\(y\)` takes the value of
`\(-22\)` , confirming Option A as the correct answer. This process involves plugging in the given
`\(x\)-` value into the equation to find the corresponding
`\(y\)` -value.

Understanding the relationship between points and equations is fundamental in algebra. In this case, the point
`\((-1, y)\)` represents a specific coordinate on the graph of the equation
`\(y = 22x\).` By substituting
`\(x = -1\)` into the equation, we find the corresponding
`\(y\)` -value for that point, which is
`\(-22\).` Therefore, the correct option is
`\(y = -22\).`

In summary, (Option A).the calculation involves substituting the given
`\(x\)-` value into the equation to determine the corresponding
`\(y\)` -value. The solution
`\(y = -22\)` aligns with the point
`\((-1, y)\)` lying on the graph of
`\(y = 22x\)`, confirming Option A as the correct choice.
