Answer:
m = -3/5
Step-by-step explanation:
slope form is y = mx + b and we are solving for m, the slope
first, isolate y on one side by moving x to the other side:
5y = -3x - 2
second, divide everything by y, so that y does not have a coefficient
y = -3/5x - 2/5
m = -3/5
Answer: D.
The y-intercept of the line means that the weight of the empty jar is about 160 grams.
Step-by-step explanation:
We know that the equation of line is given by
, where m is the slope of the line and c is the initial amount .
For the given linear equation ![y=4.95x+160.03](https://tex.z-dn.net/?f=y%3D4.95x%2B160.03)
where x is the number of marbles added, and y (dependent variable ) is the weight of the jar.
Slope of line m= 4.95 which is approximately 5 , thus, for every increase in marble, weight of jar increased by approx 5 gram.
To find the y intercept , put x=0, we get
y=160.03 which means if there is no marble then the weight of the jar = 160.03 grams or approximately 160 grams.
Thus, The y-intercept of the line means that the weight of the empty jar is about 160 grams.
You could not you can use prime factor like 1. or prime factorization like 7x3x3
