Question

The equation for line c can be written as y=–67x–1. line d is parallel to line c and passes through (10,–9). what is the equation of line d?write the equation in slope-intercept form. write the numbers in the equation as simplified proper fractions, improper fractions, or integers.

Answer 1

y = -6/7x - 3/7 or 7y = -6x - 3

Explanation:

I'm guessing you mean line c: y = -6/7x - 1

Parallel lines have same slope => line d will have slope = -6/7

y = mx + b

-9 = -6/7(10) + b

-9 = -60/7 + b

b = 60/7 - 9 = 60/7 - 63/7 = -3/7

y = -6/7x - 3/7

or 7y = -6x - 3
