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>

jek_recluse [69]

Answer:

1.1, 12, 99

Step-by-step explanation:

For the first one, we divide 2.5 by 2.2 (2.5/2.2) to get approximately 1.1 kilograms. So it would be the first option. For the second one, we know that 8x6=48, so we multiply 2 by 6 to get 12/48, so it would be the second option. For the third one, we can do this problem: 110/20 to get 5.5. We can multiply 18 by 5.5 to get 99. So that means the answer would be the first option.

Find an equation of the circle that has center (6, 2) and passes through (-2,-6).
Irina18 [472]

Answer:

(x - 6)² + (y - 2)² = 128

Step-by-step explanation:

Given as the circle has center ( 6 , 2)

and it passes through points (-2 , -6)

Now , standard equation of circle is (x -a)² + (y- b)² = r²   , where (a , b) is center and r is the radius .

Again from given center the circle equation is

(x- 6)² + (y- 2)² = r²

Now this circle passes through points (-2 , -6)

so, (-2 -6)² + (-6 -2)²  = r²

so, 8²  + 8² = r²

Or, 128  = r²

i.e Radius pf this circle = 8\sqrt{2}

Hence the circle equation formed is

(x- 6)² +( y-2)² = 128   Answer
