Question

Find the x and y intercepts and graph the equation plotting the intercepts.
-3x - 7 y = 21

Answer 1

hint:

change it to the form \[\frac xa + \frac yb = 1\]

a and b will be your x intercept and y intercept, respectively

Answer 2

For x intercept put y=0 and for y intercept put x = 0, and simplify.

Answer 3

\(x\)-intercept: let y = 0 and solve for x.
\(y\)-intercept: let x = 0 and solve for y.

Now, when you get the intercepts, mark them as two points that lie on the line.
Then just pass a line through them :)
