Using the quadratic formula to solve 4x2 – 3x + 9 = 2x + 1, what are the values of x? startroot 1 plus-or-minus startroot 159 endroot i over 8 endfraction startroot 5 plus-or-minus startroot 153 endroot i over 8 endfraction startroot 5 plus-or-minus startroot 103 endroot i over 8 endfraction startroot 1 plus-or-minus startroot 153 endroot over 8 endfraction

For this case we have that a quadratic equation is of the form:

The roots are given by:

We have the following equation:

We look for the roots:

We have to:

So:

We have two imaginary roots:

b is the answer that makes most sense

step-by-step explanation:

step-by-step explanation:

let

we know that

the y-intercept is the y-coordinate of the point when the value of x is equal to zero

so

the y-coordinate of the point a is the y-intercept

the answer part a) is

the value of y-intercept is

part b) find the slope m

we know that

the value of the slope is equal to

substitute the values

therefore

the answer part b) is

the value of the slope is equal to

the general answer is

the slope is

the value of y-intercept is
