Which best explains why the equation 3x+ 8 = 3x-5 has no solutions?
OA. The equation is true for any value of x.
OB. The equation has a variable on both sides.
OC. The equation is not true for any value of x.

OC

Step-by-step explanation:

The x value is the same on both side of the equation but the other number are not (8≠-5) so the equation can't be true no matter the value plugged for x

x=-2

infinite number of lines, so there is an infinite number of equations.

step-by-step explanation:

there are an infinite number of line that passes through the point (-2,5)

x=-2   is one line that passes through the point

y = 5 is another line that passes through the point

(these two lines are perpendicular to each other).

since the number of   numbers are infinite and the slope is the ratio of two numbers,(change in y over change in x) we can have an infinite number of slopes.     our only condition is that it passes through the point (-2,5)
