Slope is also seen as the variable “m” in y=mx+b (slope intercept form).
When we look at both equations, m=-3 because -3 lines up with m.
To find the slope of this particular number, you would need to put a 1 under -3 to make it a fraction. (-3/1)
Since the fraction three over one is negative, this will be a negative slope.
Starting at y=7 , or the point (0,7) (y intercept will be interpreted as “b” in this equation) you would need to go DOWN 3 units (boxes) , and RIGHT 1.
Once you’ve plotted at least 3 points, take a straight edge, connect the dots and extend the line. Don’t forget to put arrows at the end of the line!!
Least -> Greatest:
.4 ; 1.2 ; 1.7 ; 2.5 ; 3
Hope this helps!
Step-by-step explanation:
You can use the unituary method in this one
First card:
$25/750 min
divide both sides by 750 to figure out how many $ per min the calling card would be
25/750=0.033333333333333333333333333333333333333
750/750=1
the first card costs $0.03333333(going on)/min
Second card
$40/1,300 min
Divide both sides by 1,300
40/1300=0.03076923
1300/1300=1
Second card costs $0.03076923/min
$0.03076923<$0.03333333(going on)
therefore the second card is the better deal
The decimal value is 0.25
