Does (8,2) make the equation y=4x true? yes no

Identify Given Point and Equation: Identify the given point and the equation. The given point is (8,2), and the equation is y=4x. We need to check if the point satisfies the equation by plugging the x-value from the point into the equation and seeing if the resulting y-value matches the y-value from the point.Substitute X-Value: Substitute the x-value from the point into the equation. The x-value from the point is 8. Substitute it into the equation y=4x to get y=4(8).Perform Multiplication: Perform the multiplication to find the expected y-value. Calculating y=4(8) gives us y=32.Compare Y-Values: Compare the calculated y-value with the y-value from the point. The calculated y-value is 32, but the y-value from the point is 2. Since 32 does not equal 2, the point (8,2) does not satisfy the equation y=4x.

Identify Given Point and Equation: Identify the given point and the equation. $\newline$ The given point is $(8,2)$ , and the equation is $y=4x$ . $\newline$ We need to check if the point satisfies the equation by plugging the $x$ -value from the point into the equation and seeing if the resulting $y$ -value matches the $y$ -value from the point.
Substitute X-Value: Substitute the $x$ -value from the point into the equation. $\newline$ The $x$ -value from the point is $8$ . Substitute it into the equation $y=4x$ to get $y=4(8)$ .
Perform Multiplication: Perform the multiplication to find the expected $y$ -value. $\newline$ Calculating $y=4(8)$ gives us $y=32$ .
Compare Y-Values: Compare the calculated $y$ -value with the $y$ -value from the point. $\newline$ The calculated $y$ -value is $32$ , but the $y$ -value from the point is $2$ . Since $32$ does not equal $2$ , the point $(8,2)$ does not satisfy the equation $y=4x$ .
