Answer:

See attachment.

Explanation:

Slope-intercept form of a linear equation:


y=mx+b

where:

  • m is the slope.
  • b is the y-intercept.

Given:

  • slope = -4
  • y-intercept = -1

Substitute the given values into the general formula to create an equation for the line:


\implies y=-4x-1

Graph the line

As the slope is negative, the line slopes downwards (as the x-value increases by 1, the y-value decreases by 4).

The y-intercept is the point at which the line crosses the y-axis, so when x = 0. Therefore, place a point at (0, -1).

Substitute any other value of x into the equation of the line to find another point on the line:


x=2 \implies y=-4(2)-1=-9 \implies (2,-9)

Plot point (2, -9).

Draw a straight line through both plotted points.
