What is the equation of the line that passes through the point negative 7 comma 21 and is parallel to the line y equals 1-sevent
2 answers:
Answer:
Step-by-step explanation:
For a line to be parallel to another, it must have an equivalent slope. The equation, , is in slope-intercept form. Thus, the slope of both lines must be -1/7. Then, using the slope-intercept formula, plug in 7 for x and 21 for y to get:
Thus, the slope of the line is: .

For this case what you should see is that you have two similar triangles.
We then have the following relationship:
((AB) / (BX)) = ((CD) / (DX))
We cleared CD:
CD = ((AB) / (BX)) * (DX)
Substituting the values:
CD = ((12) / (5)) * (2.5)
CD = 6
Answer:
CD = 6
