Y = x^2 - 2x - 8 i need the y-intercept , the vertex , and the axis of symmetry

Aloiza [94]

The answer would be
vertex = (1,-9)
y- intercept = (0,8)
axis of symmetry= x = 1

i hope this helped :)

HELP ME FIND THE SLOPE

Tomtit [17]

Answer:

$m=\frac{-5}{2}$

General Formulas and Concepts:

Pre-Algebra

Order of Operations: BPEMDAS

Algebra I

Slope Formula: $m=\frac{y_2-y_1}{x_2-x_1}$

Step-by-step explanation:

Step 1: Define

Choose any 2 points from the chart.

Point (-6, 11)

Point (-2, 1)

Step 2: Find slope m

Substitute: $m=\frac{1-11}{-2+6}$
Subtract/Add: $m=\frac{-10}{4}$
Simplify: $m=\frac{-5}{2}$

If (-2,11)and(9,22) are two anchor points on the trend line, then find the equation of the line

Elza [17]

Answer:

The equation of the line is $y=x+13$

Step-by-step explanation:

step 1

Find the slope

The formula to calculate the slope between two points is equal to

$m=\frac{y2-y1}{x2-x1}$

we have

(-2,11) and (9,22)

substitute

$m=\frac{22-11}{9+2}$

$m=\frac{11}{11}$

$m=1$

step 2

Find the equation in slope intercept form

$y=mx+b$

where

m is the slope

b is the y-intercept

we have

$m=1$

$point\ (-2,11)$

substitute in the equation and solve for b

$11=(1)(-2)+b$

$11=-2+b$

Adds 2 both sides

$b=11+2\\b=13$

The equation of the line is

$y=x+13$
