Answer:

Hey buddy, here is your answer. Hope it helps yo.

Step-by-step explanation:

Let the unknown number be x,

x * 3=87. To find out the x we need to divide 87 by 3. That gives you 29. So the unknown number is 29. 29*3=87.

Using the slope and the y-intercept, graph the line represented by the following equation. Then select the correct graph. x - y
Marizza181 [45]

The graph that represents the given line with slope and y-intercept is as attached below.

<h3>How to interpret Linear Graphs?</h3>

We are given the equation;

x - y - 3 = 0

Now, the standard way we should put the equation would be in slope intercept form which is; y = mx + c

where;

m is slope

c is y-intercept

Thus, our equation can be rearranged to get;

y = x - 3

Thus, y-intercept is c = -3

The graph that represents the given line is as attached below.
