1,3,5 because they are all negatives less than -3
Answer: (4,-4)
y=-4, x=4
Step-by-step explanation:
-4x=4y
4x-8y=12
-8y=-4x+12 Now I can substitute -4x for 4y
-8y=4y+12
-2y=y+12
-3y=12
y=-4
-4x=4y
-4x=4(-4)
x=4
Answer:
13.4
Step-by-step explanation:
Answer: -2-8= -10
4+1 = 5 (the negative switches to a positive)
Your slope equals -10/5. You can look at this in a fraction for when you might use it later in point slope or slope intercept form, or you can just simplify it to -2. It might also be helpful to remember the numerator as the rise and the denominator as run, or “rise over run” if you need to graph it.
Slope = -10/5 or -2
Step-by-step explanation:
Slope, often referred to as the variable “m” can be found by solving y2-y1/x2-x1. You can do it the opposite way, though make sure the y-values are on the top.
let us represent the question with a diagram for better understanding.
Using Pythagoras theorem
