Question

Find the values of y in the following table if $y=5x+4$ is the linear relationship between x and y.

Answer 1

Let’s substitute the values of x to solve for each blank in the table.

Case (i): $x=10$
$y=5\left(10\right)+4=50+4=54$
$\left(i\right)\to 54$

Case (ii): $x=22$
$y=5\left(22\right)+4=110+4=114$
$\left(ii\right)\to 114$

Case (iii):$x=30$
$=5\left(30\right)+4=150+4=154$
$\left(iii\right)\to 154$

Case (iv): $x=40$
$y=5\left(40\right)+4=200+4=204$
$\left(iv\right)\to 204$
Therefore, the correct order is $\left(i\right)\to 54,\left(ii\right)\to 114,\left(iii\right)\to 154,\left(iv\right)\to 204$
$\to$
Option C is correct.
