Question

is (1, 7) a solution to the equation $y = 7x$?
yes
no

Explanation:

Step1: Identify x and y values

From the point \((1, 7)\), \(x = 1\) and \(y = 7\).

Step2: Substitute into the equation

Substitute \(x = 1\) into the right - hand side of the equation \(y = 7x\). We get \(7x=7\times1 = 7\).
The left - hand side of the equation is \(y = 7\). Since the left - hand side (value of \(y\)) is equal to the right - hand side (\(7x\) when \(x = 1\)), the point \((1,7)\) satisfies the equation \(y = 7x\).

Answer:

yes
