Answer:
The coordinates of H′ are (-2,0).
Step-by-step explanation:
It is given that square EFGH stretches vertically by a factor of 2.5 with respect to the x-axis to create rectangle E′F′G′H′. 
If a figure stretches vertically by a factor of 2.5 with respect to the x-axis, then the x-coordinates remains same and the points which lie on the axis are also remains the same after stretch.
It is given that the coordinates of H are (-2,0). This point lie on the x-axis, therefore it will remains the same after stretch.
Therefore the coordinates of H′ are (-2,0).
 
        
                    
             
        
        
        
Answer:

Answer:
1 ) y = 2x - 1
slope = 2
y intercept is (0,-1)
2) y = -1/2x + 5
slope = -0.5
y intercept  = (0,5)
