To graph the line
, you’ll see a steep line going downwards with a negative slope. The slope of -4 means for every unit you move right, you move down 4 units, making it quite steep! Now, when you drag the red point to the coordinates
, this point sits above the line since the y-value is greater than what the line would predict at that x-value.
Next, to find the x-intercept of line L, which is perpendicular to our original line and passes through the point
, remember that perpendicular lines have slopes that are negative reciprocals of each other. So, if the slope of our original line is -4, the slope of line L will be
. Using point-slope form from point
, we can find the equation of line L. Solving for the x-intercept, you’ll discover it crosses the x-axis at the ordered pair
.
