What is the slope of the line? _______

The equation y = −4/3x was shifted_______ to get the graph of y=−43x −5

1 answer

The slope of the line given by the equation \( y = -\frac{4}{3}x \) is \( -\frac{4}{3} \).

To determine how the line was shifted to obtain the graph of \( y = -43x - 5 \), we need to first identify the slope and y-intercept of both lines.

The equation \( y = -43x - 5 \) has:

  • Slope = \( -43 \)
  • Y-intercept = \( -5 \)

The change in slope from \( -\frac{4}{3} \) to \( -43 \) indicates a significant steepening of the line. However, there's likely a misunderstanding regarding the slope because from the manipulation of these two equations, we could infer a scaling error rather than a simple shift, as slopes are not transformed linearly via shifts.

To find out how the y-intercept shifted:

  1. The original line has a y-intercept of 0 (since \( y = -\frac{4}{3}x \) intersects the y-axis at 0).
  2. The new line has a y-intercept of \( -5 \).

Thus, the line has been vertically shifted downwards by \( 5 \) units.

In summary:

  • The slope of the line is \( -\frac{4}{3} \).
  • The line was shifted downward by \( 5 \) units.
