What is the equation of a line, in general form, that passes through points (-1, 2) and (5, 2)?

y - 2 = 0
x - 2 = 0
y - x - 2 = 0

(-1,2)(5,2)
notice how both ur sets of points have the same y value (2).... This means u have a horizontal line with a 0 slope. Ur equation would be y = 2....in general form, it would be : y - 2 = 0

we know that

the equation of the line in standard form is equal to


Ax+By+C=0

where

A,B and C are real numbers

In this problem we have


A(-1,2)\ B(5,2)

Find the slope of the line AB

The formula to calculate the slope is equal to


m=(y2-y1)/(x2-x1)

substitute the values


m=(2-2)/(5+1)


m=(0)/(6)


m=0

The line is parallel to the x-axis

The equation of the line is the y-coordinate of the points that passes through the line


y=2

Convert to general form


y-2=0

therefore

the answer is the option


y-2=0
