Answer:
Step-by-step explanation:
You have to use the discriminant for this. If the quadratic is 
, then
a = -4, b = -3, and c = 7. The formula for finding the discriminant is
which comes from the quadratic formula, but without the square root sign. Filling in:
which simplifies down to
D = 9 + 112 so
D = 121. This is a perfect square, so the solutions will be 2 real. Just so you know, you will NEVER have a solution like the one offered in the third choice down. If you have one imaginary root, you will ALWAYS have a second by the conjugate rule.

Answer:
Step-by-step explanation:
first, we find the slope
slope = (y2 - y1) / (x2 - x1)
(8,2)....x1 = 8 and y1 = 2
(7,1)....x2 = 7 and y2 = 1
now we sub
slope = (1 - 2) / (7 - 8) = -1/-1 = 1
y = mx + b
slope(m) = 1
use either of ur points...I will use (8,2)...x = 8 and y = 2
now we sub and find b, the y intercept
2 = 1(8) + b
2 = 8 + b
2 - 8 = b
-6 = b
so ur equation is : y = 1x - 6....or just y = x - 6 <===
