What are the vertex and x-intercepts of the graph of the function given below?
olchik [2.2K]
The correct question is
<span>What are the vertex and x-intercepts of the graph of the function given below?
y = x</span>²<span>-2x-35

step 1
convert the equation in the vertex form
y+35=x</span>²-2x
y+35=(x²-2x+1-1)
y+35+1=(x²-2x+1)
y+36=(x-1)²------> equation in the vertex form

the vertex is the point (1,-36)

the answer Part a) is
the vertex is the point (1,-36)

Part b) Find the x-intercepts
we know that
the x-intercepts is when y=0
so
y+36=(x-1)²
for y=0
(x-1)²=36
(+/-)(x-1)=√36-------> (+/-)(x-1)=6
(+)(x-1)=6------> x=6+1-----> x=7
(-)(x-1)=6-----> x=1-6-----> x=-5

the x-intercepts are the points
(7,0)  and (-5,0)

the answer part b) is 
the x-intercepts are the points (7,0)  and (-5,0)

the total answer is the option 
<span>A. Vertex: (1, -36); x-intercepts: (7, 0) and (-5, 0)</span>

Write the equation of the line in Point-Slope Form
katrin [286]

17.

The point-slope form:

y-y_1=m(x-x_1)

We have slope=m=8, and the point (-5, -3). Substitute:

y-(-3)=8(x-(-5))\\\\\boxed{y+3=8(x+5)}


18.

The formula of a slope:

m=\dfrac{y_2-y_1}{x_2-x_1}

We have the points (3, 4) and (15, 10). Substitute:

m=\dfrac{10-4}{15-3}=\dfrac{6}{12}=\dfrac{1}{2}

The point-slope form:

\boxed{y-4=\dfrac{1}{2}(x-3)}

or

\boxed{y-10=\dfrac{1}{2}(x-15)}
