Question

Find three points that belong to the graph and use them to sketch the graph of the equation: y = −3 −x

Answer 1

Answer:

To find a point that belongs to the graph, you have to assume the value of one variable and compute the other one. For example, if x = 0, then y = -3 -0 = -3. Similarly:

x   y

0   -3

1    -4

2    -5

To make the graph, locate the previous points on the coordinate plane and then draw the line that passes through them (see figure attached)
