Answer:
As eq of line passing through 2 points is
y-y1 = (y2-y1)/(x2-x1) ][ x -x1)
where (X1,y1)( x2, y2) denotes points lying on line
substitute (X1 ,y1) by( -1,-2) and (X2,y2) by( 2,4)
y+2 = 6/3 )( x+1)
y+2= 2x +2
y = 2x is required equation
Answer: 10^2
Step-by-step explanation:
43.27×9.1=
393.757
Estimate. 400
10×10=100×10=1000
This is wrong because the estimated number is oy 400.
So, 10×10=100
The answer is 10^2.
475 songs- 380 songs= 95 songs
95 songs/ 475 songs* 100%= 20%
The percent error is 20%~
Shifted up
For example: if f(x) = x^2 + 4, the parent function has a vertex at (0,0), but the +4 shifts the graph up 4 units on the y-axis so the vertex would be (0,4)
