Question

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-seventh x minus 56?

Answer 1

Answer: $y=-\frac{1}{7} x+22$

Step-by-step explanation:

For a line to be parallel to another, it must have an equivalent slope.  The equation, $y=-\frac{1}{7} x-56$, 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:

$21=-\frac{1}{7} *7+b$

$21=-1+b$

$22=b$

Thus, the slope of the line is: $y=-\frac{1}{7} x+22$.

Hope it helps :D
