How do you graph a linear equation?
for example, -18x+9y=72

The graph of given equation is shown below.

Step-by-step explanation:

We need to draw the graph of linear equation.

Let as consider a linear equation.

First we need to find any two points on the line. So, will find x and y-intercept of the line.

Substitute x=0 in the given equation to find the y-intercept.

Divide both sides by 9.

⇒ y-intercept of the line is 8.

Substitute y=0 in the given equation to find the x-intercept.

Divide both sides by -18.

⇒ x-intercept of the line is -4.

Now, plot these two points (0,8) and (-4,0) on a coordinate plane and connect them by a straight line.

Therefore, the graph of given equation is shown below.

answer: a. 13/44

step-by-step explanation: judging by the information given to us, we are looking for experimental probability. we can see that 13 males have chosen chocolate ice cream. there are 44 ice creams in total (remember that the total is always the denominator). so our answer is 13/44.
