Answer:
y=-1/3x-2
Step-by-step explanation:
First off, lets outline that parallel lines have the <u>Same Slope</u>. So we can plug in -1/3 as our slope, or m.
Lets plug in -1/3 as our slope in Point Slope form to find the y intercept. Point slope form should be attached in an image below.
1) Plug slope and points into point slope form:
y+1=-1/3(x+3)
2) Distribute -1/3 to x and 3:
y+1=-1/3x-1
3) Subtract 1 from both sides:
y=-1/3x-2
Now we have our answer is slope intercept form!

A graph of linear function is a straight line.
Linear function in a slope-intercept form: y = mx + b
Answer: Equation 3: y = 12x + 17.

subtitute x = 2 to the equation (*):
Answer: (2, 13)
3.
(-2; 7), (-5; 4)
the slope:

The conclusion: It's a linear function
Answer: It is a linear function because there is a constant rate of change in both the input and output values.
4.
y = 3x + 5 /look at the picture/
Answer: It is a linear function because its graph contains the points (0, 5), (1, 8), (2, 11), which are on a straight line.
