Question

What is the equation of the line that passes through the point (-7,-7) and has a slope of 11?

Answer 1

y = 11x + 70

Explanation:

The equation of a line in slope- intercept form is

y = mx + c ( m is the slope and c the y- intercept )

Here m = 11 , then

y = 11x + c ← is the partial equation

To find c substitute (- 7, - 7 ) into the partial equation

- 7 = - 77 + c ⇒ c = - 7 + 77 = 70

y = 11x + 70 ← equation of line

Answer 2

y = 7 is the equation of the line that passes through the point ( -2, 7 ) and has a slope of zero.

Explanation:

Given:

Let,

A ≡ ( x1 , y1 ) ≡ ( -2, 7 )

Slope = m = 0

To Find :

Equation of Line:

Solution:

Formula for , equation of a line passing through a point ( x1 , y1 ) and having a slope m is given by

Now substituting the values of x1 = -2 and y1 = 7 and slope m = 0 we get,

Which is the required equation of a line passing through the point ( -2, 7 ) and slope zero
