Answer: The required value of y is 22.
Step-by-step explanation: We are given the following function of a and b :

We are to find the value of y when a = 1 and b = 2.
To find the required value of y, we need to substitute the values of a and b in equation (i).
From (i), we get

Thus, the required value of y is 22.

Hello!
Are you in algebra?
Here is how to solve and graph.
First, look for the slope and y-intercept of your equation.
y = - 1/2r-6
The y intercept is, -6
The slope is -1/2
the variable r, is another way to represent x, as it is just a variable.
now that you have all that information, plot -6 on the graph, -6 should be on the y- axis.
from that point, move down one space and move right two space. complete this step multiple times.
Now please look at the photo, and Here's what the graph should look like.
