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

Explanation:

y= -1/7 + 22

Answer 2

Answer:
`y=-(1)/(7) x+22`

Explanation:

For a line to be parallel to another, it must have an equivalent slope. The equation,
`y=-(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=-(1)/(7) *7+b`

`21=-1+b`

`22=b`

Thus, the slope of the line is:
`y=-(1)/(7) x+22`.
