Answer: y = -3/4x + 7
Step-by-step explanation:
first find slope:
y2-y1 / x2 - x1
1-4 / 8-4
-3/4
now just plug the slope (m) into the equation of a line using one of the points to find the y intercept
ill use (8,1)
1 = (-3/4)(8) + b
now solve :)
1 = -6 + b
7 = b
so now plug in the slope and the y intercept into the slope intercept form to find the equation of the line
y = -3/4x + 7
 
        
             
        
        
        
Answer:
5, 9, 13, 17, 21, .....
Step-by-step explanation:
To generate the sequence, substitute n = 1, 2, 3, 4, ..... into the rule
a₁ = 4(1) + 1 = 4 + 1 = 5
a₂ = 4(2) + 1 = 8 + 1 = 9
a₃ = 4(3) + 1 = 12 + 1 = 13
a₄ = 4(4) + 1 = 16 + 1 = 17
a₅ = 4(5) + 1 = 20 + 1 = 21
 
        
             
        
        
        
Answer
9.327
16*16= 256
13*13=169
256-169=87
87 squared=9.32737905309
9.32737905309 ROUNDED TO NEAREST THOUSANDTH= 9.327
