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
