Answer: the Second step is to divide 4 from each sides
Step-by-step explanation:
Answer: the second option is correct
Using Slope = rise/run .
You can create a graph to see the intercepts (attached) OR
Step-by-step explanation:
To find the y-intercept, figure half way between (-1, -2) and (1, 2/3)
Half of that is
below the origin, y-intercept is
or
to create an equation for this:
Take the difference in y-values
which simplifies to 4 for the Rise
Take the difference in x-values
so the Run is 6
The slope is the slope is 4/6 , the same as 2/3.
Use slope intercept form to create the equation:
You can compute the x-intercept by substituting 0 for y
0 = 2x/3 - 4/3 . 4/3 = 2x/3 multiply both sides by 3
4 = 2x divies both sides by 2 to get 2 = x, the x-intercept
