Answer:
C, [tex]y = 3x - 1[/tex]
Step-by-step explanation:
the function's y-values increase by 3 at each interval. (rise)
the function's x-values increase by 1 at each interval. (run)
[tex]\frac{rise}{run} = \frac{3}{1}[/tex]
the slope is [tex]3[/tex]
but, you still have to find the y-intercept
[tex]b=y-mx[/tex]
with b representing the y-intercept and m representing the slope of the line
and x and y are the values from a point on the table: (-2,-7).
[tex]b=-7-(3)(-2)[/tex]
[tex]b=-7+6[/tex]
[tex]b=-1[/tex]
Therefore the equation of the line is [tex]y = 3x -1[/tex]
