Isn't the line of symmetry -b/2a?

The equation of the line of symmetry of a curve is the equation of the line dividing the given curve into two equal parts.

The formula for the equation of a line is:

y=mx+c

Where:

y= the y coordinates

m= the slope

x= the x coordinates; and

c= the y intercept of the line

Slope is find by using the formula:

m=y2-y1 / x2-x1

Then we find the value of 'c' by plugging in the values and finally write down the equation in the form of the equation mentioned above.

y=mx+c

Where:

y= the y coordinates

m= the slope

x= the x coordinates; and

c= the y intercept of the line

Slope is find by using the formula:

m=y2-y1 / x2-x1

Then we find the value of 'c' by plugging in the values and finally write down the equation in the form of the equation mentioned above.

7-8=d-s

Y = mx + c

y= y coordinates

m= slope=y2-y1 / x2-x1

x= t x coordinates; and

c= y intercept of the line

y= y coordinates

m= slope=y2-y1 / x2-x1

x= t x coordinates; and

c= y intercept of the line

F(x)=-2x^2+2x+1
