(-4,2) ;m=-1/3 You have to use this formula y=mx+b
1 answer:
Answer:
y = -1/3x +2/3
Step-by-step explanation:
We assume you want the equation of the line through the given point. The point-slope form of the equation is a good place to start.
y -k = m(x -h) . . . . . line with slope m through point (h, k)
y -2 = -1/3(x +4) . . . . . . fill in given values
y = -1/3x -4/3 +2 . . . . . eliminate parentheses, add 2
y = -1/3x +2/3 . . . . . . . simplify

5w + 9z = 2z + 3w
Move terms with w to the left - subtract 3w from both sides
2w + 9z = 2z
Subtract 9z from both sides
2w = -7z
Divide both sides by 2
w =
Answer:
is the correct answer.
Step-by-step explanation:
We know that vertex equation of a parabola is given as:
where is the vertex of the parabola and
are the coordinate of points on parabola.
As per the question statement:
The parabola opens upwards that means coefficient of is positive.
Let
Minimum of parabola is at x = 3.
The vertex is at the minimum point of a parabola that opens upwards.
Putting value of a and h in the equation:
Formula used:
Comparing the equation formulated above with the options given we can observe that the equation formulated above is most similar to option A.
Comparing and
