A horizontal line goes through the point (–7,10). Which statements are true about this line? Check all that apply.
Nata [24]
The slope of the line is the change in y values over the change in x values, since for horizontal line, the y values do not change then, the slope is zero.

If the line is horizontal, this means that whatever the value of the x-coordinate (abscissa) is, the y-coordinate (ordinate) will always be 10. 

The intercept of the line is 10. So, third statement is not true.

Since the equation of the line is zero and its y-intercept is zero, using the equation of the line which is,
                                  y  = mx + b
where m is slope and b is y-intercept. The equation of the line is,
                                y = 0x + 10  ;   y = 10

<em>The true statements for this item are 1st, 2nd, and 4th.</em>

Solve the equation by finding square roots. To start, remember to isolate x^2. Equation= x^2+4=20
prohojiy [21]
Get the equation simplified. Subtract 4 by each side.
20-4= 16
and the square root of 16, is 4. 
Plug it in to check. 
(4)^2+4=20
16+4=20
20=20

Ultimately your final answer is X=4
