Question

Consider the following equation.- 7y = - 42Step 2 of 2: Graph the equation by plotting the x- and y-intercepts. If an Intercept does not exist, or is duplicated, use another point on the line toplot the graph.

Answer 1

The equation given is:

`-7y=-42`

by solving it for y we have that:

`\begin{gathered} -7y=-42 \\ y=(-42)/(-7) \\ y=6 \end{gathered}`

This means two things; first this in an horizontal line, second the points of the line will always have a y component equal to 6; therefore the y intercept is 6 and there is no x-intercept.

Using the y-intercept (0,6) and the point (1,6) we plot the line:
