Question

Write the equation in slope form of the line that passes through the points -2,1 and 2,1

Answer 1

Slope = 0

Explanation:

If you graph the two ordered pairs, they will be right across from each other. Then if you make a line through them, it will be straight across, and a straight horizontal line has a slope of 0.

Answer 2

The form of this line would be y = 1.

Explanation:

To find the equation of this line, start by using the slope formula to find the slope.

m(slope) = (y2 - y)/(x2 - x1)

m = (1 - 1)/(2 - -2)

m = 0/4

m = 0

Now that we have the slope, we can use it along with either point in point-slope form (which is below). Solve for y to get the equation.

y - y1 = m(x - x1)

y - 1 = 0(x - 2)

y - 1 = 0

y = 1
