So for a linear line to be parallel to another line, they have to have the same slopes. The given line has a slope of -.75
If we use the point slope formula, which is y - y1 = m( x - x1 ) we can plug in the slope and the point that the line must go through to get the new line.
y - 0 = -.75( x - 8 )
y = -0.75x + 6
The equation of the line that is parallel to y = -0.75x and passes through (8,0) is
Discriminant reviewThe discriminant is the part of the quadratic formula underneath the square root symbol: b²-4ac. The discriminant tells us whether there are two solutions, one solution, or no solutions.
