You use the discriminant (b²-sqr(4ac))/2a and if sqr(4ac) inferior to 0 then use i = sqr(-1)

Answer:
y = 5 -2/3 ( x-9)
Step-by-step explanation:
point slope form
y = y0 + m(x - x0).
m is the slope
m = (y2-y1)/(x2-x1)
( 7-5)/(6-9)
2/-3
=-2/3
The slope is -2/3
Using the point (9,5)
y = 5 -2/3 ( x-9)
Answer:
Hope it helps you ,hope it is clear. I used completing the square method.
Answer:
so if x = 0, x = 2, and x = 4
3(0) + 2 = 0 + 2 = 2, so when x = 0, y = 2
3(2) + 2 = 6 + 2 = 8, so when x = 2, y = 8
3(4) + 2 = 12 + 2 = 14, so when x = 4, y = 14
