Algebra I

Coordinates (x, y)
Slope Formula: $\displaystyle m = \frac{y_2-y_1}{x_2-x_1}$

Step-by-step explanation:

Step 1: Define

Identify

Point (6, 8)

Point (6, 6)

Step 2: Find slope m

Simply plug in the 2 coordinates into the slope formula to find slope m

Substitute in points [Slope Formula]: $\displaystyle m = \frac{6-8}{6-6}$
[Fraction] Subtract: $\displaystyle m = \frac{-2}{0}$
Simplify: m = undefined

∴ We have a vertical line at x = 6.

When asked his age, the algebra teacher said, “if you square my age, then subtract 23 times my age, the result is 50.” how old i

Natalka [10]

Let the age be x.

Given,

$x^{2} - 23x = 50$

$x^{2} - 23x - 50 = 0$

$x^{2} - 25x + 2x - 50 = 0$

$x(x -25)+2(x-25)=0$

$(x+2)(x-25)=0$

Hence, x = -2 or 25.

Since, the age of the teacher cannot be in negative, the age of the teacher is 25 years.
