The steepness of a line is determined by its slope. The value of "k" is 0
First, we need to find the slope of the line passing through the points A (-8, 0) and B (8, 0) as shown:
To get the value of k, we will equate the slope of the perpendicular line which is 0 to the slope of the line passing through A (-8, 0) and (0, k)
Hence the value of "k" is 0

If I recall correctly, the slope-intercept form is y=mx+c or y=Mx+b
c is always the y-intercept of the graph, being the point where the line crosses the y axis. In this case:
c= -1
To get the slope, we can use the following equation:
m=(y2-y1)/(x2-x1)
All we need to do is substitute in two sets of coordinates. In this case we will use the coordinates highlighted with the bold points:
(1;2)
(-1;-4)
Now we will place the coordinates into the equation, making sure to correspond its x value to its y value:
m=(-4-2)/(-1-1)
m=3
Therefore the equation is y=3x-1
