Solve the system of equations by graphing: -1/3x + y=-1, y=4+1/3x

Answers

Answer 1

Answer:

$-(1)/(3)x$ + y = -1 ⇒ y = $(1)/(3)x$ - 1

To graph this line, plot a point at the y-intercept (0, -1), than plot the next point using the rise over run from the slope $((1)/(3))$ by counting up 1 and to the right 3 of the y-intercept. This gives you a second point of (3. 0). Draw a line through those two coordinates.

Answer: Plot (0, -1) and (3, 0) and draw a line through them.

y = 4 + $(1)/(3)x$ ⇒ y = $(1)/(3)x$ + 4

Same as above. Plot the y-intercept (0, 4) and then use rise over run from the slope to plot (3, 5).

Answer: Plot (0, 4) and (3, 5) and draw a line through them.

You should end up with two PARALLEL lines. Since the lines never intersect, there are no solutions to this system of equations.

Answer: No Solution
