Answer:
The slope of line for given points is
Step-by-step explanation:
Given points of line as :
A = ( - 7 , 15 ) i, e = - 7 ,
= 15
B = ( 10 , 27 ) i.e = 10 ,
= 27
Let The slope of line be m
So , The slope with two points is given as equation
m =
Or, m =
Or, m =
Hence The slope of line for given points is . Answer
Answer:
d. The equation has one solution and there is not enough information to determine the direction of the parabola.
Step-by-step explanation:
For a general quadratic equation
y = ax² +bx +c
the solution is
The discriminant (D) is the part of the quadratic formula underneath the radical: b² - 4ac.
D tells us whether there are
- two different real solutions
- two identical real solutions ("one solution")
- two complex solutions.
If D= 0,
and there are two identical solutions ("one solution").
The direction of the parabola depends on the sign of a.
That information is not given, so we cannot determine the direction of the parabola.
