Answer:
-4
Step-by-step explanation:
We have the coordinates (6, 3) and (8, 4), allowing us to calculate the slope (or gradient). To do this, you divide the change in y by the change in x, which is 1/2 which is a half.
The form of a linear equation is y = mx + c, where m is the gradient and c is the y-intercept.
We have the gradient, so we can put it in the equation:
y = x/2 + c
We can now substitute in a pair of our coordinates and rearrange to find the y-intercept.
3 = 6/2 + c
3 = 3 + c
c = 0
Therefore the equation for our line is y = x/2.
We can now put in the y coordinate we were given to work out the corresponding x coordinate:
-2 = x/2
x = -4
Therefore n is -4.

Answer:
option 3
Step-by-step explanation:
Larger the value of '' a '' makes the parabola narrow.
A positive value of '' a '' which is close to 0 makes the parabola wide.
<em><u>To find the widest graph , find the smallest </u></em><em><u>a</u></em><em><u>. (or </u></em><em><u>a</u></em><em><u> closest to zero)</u></em>
option 1

option 2

option 3

option 4

Positive and negative value of ' a ' decides the direction the parabola opens.
But we have to find the widest parabola irrespective of the direction.
So we will find the smallest ' a '
