Answer:
To simply or reduce fraction by dividing both the numerator and denominator by a number they are both divisible by.
Example:
3/12 both numbers are divisible by 3 do divide it and it becomes 1/4
Answer:
y = -4x - 32
Step-by-step explanation:
First, find the slope using rise over run (y2 - y1) / (x2 - x1)
Plug in the points:
(y2 - y1) / (x2 - x1)
(8 - 4) / (-10 + 9)
4 / -1
= -4
So, the slope is -4. Plug in the slope and a point into y = mx + b, and solve for b:
y = mx + b
4 = -4(-9) + b
4 = 36 + b
-32 = b
Then, plug in the slope and y intercept into y = mx + b
y = -4x - 32 is the equation of the line
Answer:
x = -5, 1
Step-by-step explanation:
To factor an equation, break the polynomial into two binomials which multiply to make it. Find two numbers that multiply to C and add to B from
.
-1 and 5 multiply to -5 and add to 4.

The zeros are the factors set equal to 0 and solved.
(x+5) = 0
