Answer:

(1, 0) and (3, 0)

Step-by-step explanation:

y=2x²-8x+6

x- intercept when y=0

  • 2x²-8x+6=0
  • x²-4x+4=1
  • (x-2)²=1
  • x-2=1 ⇒ x= 3
  • x-2= -1 ⇒ x= 1

Answer:

Rewrite the function as an equation.

y

=

Use the slope-intercept form to find the slope and y-intercept.

Tap for fewer steps...

The slope-intercept form is  

y

=

m

x

+

b

, where  

m

is the slope and  

b

is the y-intercept.

y

=

m

x

+

b

Find the values of  

m

and  

b

using the form  

y

=

m

x

+

b

.

m

=

b

=

The slope of the line is the value of  

m

, and the y-intercept is the value of  

b

.

Slope:

Any line can be graphed using two points. Select two  

x

values, and plug them into the equation to find the corresponding  

y

values.
