The answer is y=-4/7x+7. You simply substitute in the given numbers. -4/7 for the slope (m) and 7 for the y-intercept (b). 
        
             
        
        
        
Answer:
-35/6
Step-by-step explanation:
We need to find the value of x , And the given pair of Rational numbers are equal. 
<u>Question</u><u> </u><u>(</u><u>I)</u><u> </u><u>:</u><u>-</u><u> </u>
→ 3/4 = 7/x 
→ 7/x = 3/4
→ 1/x = 3/4 × 1/7 
→ 1/x = 3/28 
→ x = 28/3 
<u>Question</u><u> (</u><u>ii)</u><u> </u><u>:</u><u>-</u><u> </u>
→ x/7 = -5/6 
→ x = -5/6 × 7 
→ x = -35/6 
<h3>
• Hence the value of x is -35/6 .</h3>

Triangle=1/2 times base times height
base=32
height=24
the lateral surface area is not including bottom so just the 4 side triangles
4 times 1/2 times base times height
4 times 1/2 times 32 times 24
2 times 32 times 24
1536
lateral surface area is 1536 square centimeters
