Answer:
see below
Step-by-step explanation:
y = x^2 - 6x + 14 'complete the square for 'x'
x^2 - 6x + 9 - 9 + 14
y = (x-3)^2 + 5 vertex from <u> vertex = (3,5) </u>
since the coefficient of ^2 is positive it is a bowl shaped parabola and the vertex is a <u>MINUMUM</u>
vertex
The slope is 3. You can find it by doing 0 - (-4), which is 4 and 4/3 - 0, which is 4/3. Then you divide 4 / (4/3), which is 3.
Answer:
y intercept is -23
Step-by-step explanation:
Here we are given three coordinates and are asked to find y intercept of the line passing through these points.
We thus find the equation of this line by two point form
the form says
(y-y1)/(x-x1) = (y2-y1)/(x2-x1)
Here (x1,y1) = ( -36 , 1 )
and (x2,y2) = ( 13,-54)
Substituting the values we get
(y-1)(x+36)=(1-13)/(-36-(-54))
(y-1)(x+36)=(-12)/(-36+54)
(y-1)(x+36)=(-12)/(18)
y-1=-2/3 ( x+36)
In order to determine the y intercept we are required to leep x = 0 in above equation and solve for y
y-1 = -2/3 (0+36 )
y-1= (-2/3) x (36 )
y-1 = -2 x 12
y-1 = -24
adding 1 on both hand sides
y = -24 +1
y=-23
