Step-by-step explanation:
Got 100% on this Test/Usa
3x^3<span> + 17</span>x^2<span> + 21</span>x<span> - 9
this is the correct answer for this problem.</span>
An easy way to answer this problem is to find the mid-point between the two given points, namely ( (4-2)/2, (1-11)/2 )=(1,-5).
Another way is to find a line through the two points, and select any point on the line.
Slope = (1-(-11))/(4-(-2))=12/6=2
Then use the point slope form to find the line:
y-1=2(x-4) which can be simplified to
y=2x-7
Put x=0, y=-7 => (0,-7)
Put x=1, y=-5 => (1, -5) [ as above ]
Put x=2, y=-3 => (2, -3)
