What is the equation, in slope-intercept form, of the line that contains the points (3, -4) and (5 -6)
Answers
Answer:
y = -x - 7
Step-by-step explanation:
As we move from the point (3, -4) to the point (5, -6), x increases by 2 and y decreases by 2. Thus, the slope of this line is m = rise / run = -2/2, or -1.
Starting with the general slope-intercept form of the equation of a straight line, we get y = mx + b => y = -1x + b.
Subbing -4 for y and 3 for x, we get
-4 = -1(3) + b, which yields b = -1
Thus, the desired equation is
y = -x - 1

Answer:
Different: Because you need to make it a fraction not a whole number
Similar: Because you are both multiplying numbers
Reasoning:
The reason for this is because if you are multiplying 1/4 to 2 it equals 2/4.
But if you are multiplying 14 and 2 you don't get 2/4 you get 28.

What is a place value?
Place value, which is related to a digit's location in a number, is the amount that each digit is worth.
Given:
The number is 284.
To round the number to the nearest hundred:
The digit in the hundredth place is 8.
And 8 > 4.
So, the number left to the number 2 will increase by 1.
And the number right next to 8 will become zero.
So, the value of 2 becomes 2 + 1,
and the rest number becomes zero.
So, 284 rounded to the nearest hundred is 300.
Therefore, the result is 300.

Answers
(x-3)(x-5)=35
Multiply the brackets together
x*x-5*x-3*x-3*5
x^2-8x+15=35
Move +35 to the other side. Sign changes from +35 to -35
x^2-8x+15-35=35-35
x^2-8x-20=0
(x-10)(x+2)=0
x-10=0 x+2=0
Move -10 to the other side. Sign changes from -10 to +10
x-10+10=0+10 x+2-2=0-2
x=10 x=-2
Answer: x=10
Just plug in the different numbers to see which ones equal 35.
I’m going to plug in x = -8 into the equation
(x - 3)(x - 5) = 35
(-8 - 3)(-8 - 5) = 35 (substitute -8 for x)
(-11)(-13) = 35
143 = 35
This answer is wrong because 143 does not equal 35
Now let’s plug in x = 10
(x - 3)(x - 5) = 35
(10 - 3)(10 - 5) = 35 (substitute 10 for x)
(7)(5) = 35
35 = 35
This solution works because 35 equals 35
