Answer:
The slope <em>m</em> is 1.9 and the y-intercept <em>b</em> is 2.5. 
Step-by-step explanation:
This is in slope-intercept form, y=<em>m</em>x+<em>b</em>, where <em>m</em> is slope and <em>b</em> is the y-intercept. 
y = 1.9x + 2.5 means that <em>m </em>is 1.9 and <em>b</em> is 2.5. 
 
        
             
        
        
        
The answer is -1/3
The slope m is:
m = (y2 - y1) / (x2 - x1)
(x1, y1) = (-2, 2)
(x2, y2) = (4, 0)
m = (0 - 2) / (4 - (-2)) = -2 / 6 = -1/3
        
             
        
        
        
<u><em>This would be k < 50.</em></u>
This inequality states that k, the price at which Nita wants to buy the new keyboard, is less than 50 dollars.

Answer:
1,570
Step-by-step explanation:
10×2=20
20×3=60
30×5=150
40×7=280
50×4=250
60×3=180
70×8=630
Now,
20+60+150+ 280 +250+ 280+ 630=1,570
this is the answer
