Answer 1

SOLUTION

TO DETERMINE

Plot a line graph for the variables x and y, where y = 2x +1.

Using the graph, find the value of

(1) y, when x = 5

(2) x, when y=13.

EVALUATION

Here the given equation of the line

$\sf{y = 2x + 1}$

Graph : Graph is referred to the attachment

From the graph we see that

(1) When x = 5 we have y = 11

(2) when y = 13 we have x = 6
