# How do you graph the line y = 3/5 x - 2?

May 19, 2018

#### Explanation:

Take the equation $y = \frac{3}{5} \cdot x - 2$ and pick 2 values of x at random and plug them in to find the corresponding value of y. For example, I choose 0 and 5.

x = 0:
$y = \frac{3}{5} \cdot 0 - 2 = - 2$

So this calculation gives you a point on the plot of the equation $y = \frac{3}{5} \cdot x - 2$
The point has coordinates (0,-2), put a dot at (0,-2).

If you need help placing the point (0,-2) on your graph, click this link.

x = 5:
$y = \frac{3}{5} \cdot 5 - 2 = 1$

So this calculation gives you a point on the plot of the equation $y = \frac{3}{5} \cdot x - 2$
The point has coordinates (5,1), put a dot at (5,1).

Because there are no exponents in the equation, the equation plots a straight line. Draw a line through your 2 dots.

I hope this helps,
