Question

Plot the intercepts to graph the equation. x+y=3

Use the graphing tool to graph the equation. Use the intercepts when drawing the line. If only one intercept​ exists, use it and another point to draw the line.

Answer 1

Answer: You will have points plotted at +3 on the y axis, and +3 on the x axis.

The attachment shows what your graph should look like.

Explanation:

The intercept is where the graphed line crosses an axis.

To find the y-intercept, substitute 0 for x and solve for y:

0 + y = 3. Subtracting 0, you have y = 3

So you can plot a point at +3 on the y axis.

To find the x- intercept, substitute 0 for y, and solve for x

x + 0 = 3 Again, subtracting 0, x = 3

So plot a point on the x-axis at +3

Use the line tool to connect the two points.
