Answer:
linear functions will create a straight line when graphed but if you were to graph a non linear equation then it would not create a straight line
Step-by-step explanation:

in slope-intercept form (y = mx + b), the "m" is the slope and the "b" is the y-intercept. so in this equation, 7 would be your slope and 8 would be your y-intercept.
slope: 7
y-intercept: 8
With this information we know that in slope-intercept form that the equation will at least look like this.
y= -2x + b.
But we have to look for b. In order to do this we are going to have to plug in (5,3) into the x and y values.
3= -2(5) + b
3= (-10) + b
13= b
We then put this b value into the slope intercept formula.
y= -2x + 13 < this is your final answer
The complete question is as follows: A Christmas gift is tied with ribbon the bow requires 47cm of ribbon, what is the total length of the ribbon in cm?
Answer: The total length of the ribbon is 177 cm.
Step-by-step explanation:
As there are 4 sides of the rectangular box and 20 cm of ribbon is on each side. This means that a total of
= 80 cm is there on the top and bottom.
Hence, length of ribbon attached at the left and right side of the box is as follows.

This means that on both left and right side a total of 50 cm is there.
Therefore, total length of ribbon is as follows.
Total length = 47 cm + 50 cm + 80 cm = 177 cm
Thus, we can conclude that the total length of the ribbon is 177 cm.
