X^2 + 18x = 0
(x^2 + 18x + 81) = 0
(x + 9)^2 = 81
x + 9 = +/-squareroot81
x = 0, and -18

What is the slope form equation?

CaHeK987 [17]

Answer:

y= mx +c

Step-by-step explanation:

The point- slope form of an equation is

y= mx +c, where m is the gradient and c is the y-intercept.

You can find the value of m by using the gradient formula.

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

Then substitute the value of m found into the equation. Next substitute a pair of coordinates the line passes through to find the value of c. Substitute the value of c and you will obtain the point-slope form equation of the line.

Here's an example.

Point-slope form of an equation passing through (1, 2) and (5, 6).

① Finding gradient, m.

$m = \frac{6 - 2}{5 - 1} \\ m = \frac{4}{4} \\ m = 1$

② Substitute value of m into equation.

y= 1x +c

y= x +c

③ Substitute a pair of coordinates.

when x=1, y=2,

2= 1 +c

c= 2 -1

c= 1

Thus the equation of the line is y= x +1.

How do i do these? (do at least one please)

meriva

32. 5^-2=1/25
5^-1=1/5
5^0=1
5^1=5
5^2=25
5^3=125

The domain are -2,-1,0,1,2,3,
The range are 1/25,1/5,1,5,25,125

So as the domain increases so does the range
