Graph the line that passes through the points -5,3 and -4,1 determine the equation
1 answer:
y = -2x - 5
Step-by-step explanation:
We begin by finding the gradient of the line;
Δ y / Δ x
(1 – 3) / (-4 - -5)
-2 / 1
So the equation, to begin with, will be;
y = -2x + c
Let's find the value of C;
This is called the y intercept and is when x=0 at the intercept
(1,3) (0,c)
-2 = c – 3 / 0 – 1
-2 = c - 3 / -1
2 = c – 3
C = -3 – 2
C = -5
The final equation is;
y = -2x - 5

So, what is the total lenght of the pieces that wer cut off?
we multiply the lenght by the number:
4
*5=20+
=21
and we subtract this from the original pipe, that is
30
-21
we need to bring the two fractions to the same denominator (by multiplying the fraction art in the first by 3 and 4 the second):
30
-21
=9 
so the correct answer is D!
