Answer:
Explained
Step-by-step explanation:
The 1 is the y-intercept
The -2 is the slope
First place a point at (0,1)
Then, because it's negative from left to right the graph is decreasing (going lower on the y-axis the farther you go on the x-axis).
Slope is rise over run so the -2 affects how far it goes. So for each value of x that increases by one, a new point will be two units down and one unit right of the previous point. To graph to the left of the y-intercept then you do that backwards where the next point is two units up and one unit left.
Then just draw a straight line connecting all the points.
Answer:
500 - 368 = 132This means that to reach 500 from 368, you will need to count 132 ones.132 can be written in several ways including:132 = 100 + 32132 = 100 + 30 + 2For the first one:the count will be 1 one hundred and 32 units to reach 500 from 368For the second one:the count will be one hundred, 30 tens and 2 ones to reach 500 from 368

Step-by-step explanation:
Answer: 8x
Step-by-step explanation:
Product stands for multiplication, so we need to use (×)
Let x = the number.
----------------------------------------------
The product of 8 and a number
8 × x=8x
Answer:
to get what he kept subtract 5 from 18, to get 13 so 13 was kept. the ratio will be kept:sold which is 13:5

Step-by-step explanation:
The value of the constant of proportionality is k=5k=5
Step-by-step explanation:
we know that
A relationship between two variables, x, and y, represent a proportional variation if it can be expressed in the form y/x=ky/x=k or y=kxy=kx
The value of the constant k is equal to the value of the slope
In this problem we have
y=5xy=5x ------> is a linear direct variation
The slope is m=5m=5
therefore
The value of the constant of proportionality is k=5k=5
