Question

Which is the equation of the given line? (-10,-7) (3,-7)

Answer 1

Explanation:

the answer is y=-7

Answer 2

Answer:
`y=-7`

Explanation:

The equation of the line in Slope-intercept form is:

`y=mx+b`

Where "m" is the slope of the line and "b" is the y-intercept.

Find the slope with this formula:

`m=(y_2-y_1)/(x_2-x_1)`

Given the points (-10,-7) (3,-7), substitute values into the formula. Then:

`m=(-7-(-7))/(-10-3)\\\\m=(0)/(-13)\\\\m=0`

Substitute the slope and any point into
`y=mx+b` and solve for "b":

`-7=0x+b\\b=-7`

Then, substituting "m" and "b" into the equation
`y=mx+b`, you get that the equation of this line is:

`y=0x-7`

`y=-7`
