m is the slope = (y2-y1) / (x2-x1) so between the y-intercept (0,-100) and the given point (25, 50) we have m= -100-50/0-25 = -150/-25 = 6
y= 6x -100
now we have to figure the inequqlity part so take point (0, 0) that belongs to the solution and substitute in the equation
0 = 6*0 -100
0 = -100 for the equation to be true we have to make it 0 > -100, we also need to make it NOT greater or equal then because the line is doted not solid so the inequality is
The ramp will form a triangle with height 2ft and base 6ft.
The length of the ramp will be the hypotenuse of this triangle. length² = height² + base² length = √(height² + base²) length = √(2² + 6²) length = √(4 + 36) length = √40 length = 6.3ft
