QUESTION:

Graph the functions: f(x)=-2x-5


ANSWER:

f(x)=-2x-5

we can write the equation as,
y = -2x-5

Now give arbitrary values t x and find corresponding values of y.

for example;

when x = 0,

y = -2(0) -5

==> y = 0 - 5

==> y = -5


when x = 1, we have y = -2(1) - 5 = -2-5 = -7

when x = -1 we have, y = -2 ( -1) -5 = 2 - 5 = -3
and so on..

Now plot these values on the graph paper...


then the graph will come like this......
