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

Point (0, -5)

Point (-2, 1)

Step 2: Find slope m

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

Substitute in points [Slope Formula]: $\displaystyle m=\frac{-5-1}{0--2}$
[Fraction - Denominator] Simplify: $\displaystyle m=\frac{-5-1}{0+2}$
[Fraction - Numerator] Subtract: $\displaystyle m=\frac{-6}{0+2}$
[Fraction - Denominator] Add: $\displaystyle m=\frac{-6}{2}$
[Fraction] Divide: $\displaystyle m=-3$

What are the solutions to the system of equations {-x+y=4 {y+12=x^2+x

Gnoma [55]

Answer:

Step-by-step explanation:

$y=4+x$ ............................................ (1)

$y=x^2+x-12$ ............................................ (2)

now equate both (1) and (2)

$4+x=x^2+x-12$

$=>x^2=16$

$x=-4,4$

now substitute the values of x ,

when $x=-4$ , y becomes 0

when $x=4$ , y becomes 8

so, solution set:

$(-4,0)$ and $(4,8)$
