ΔABC was dilated from the origin by a scale factor of 2 to create ΔA′B′C′. Which statement explains why the triangles are similar? Dilations preserve side length; therefore, the corresponding sides of ΔABC and ΔA′B′C′ are congruent.
Dilations preserve betweenness of points; therefore, the corresponding sides of ΔABC and ΔA′B′C′ are congruent.
Dilations preserve orientation; therefore, the corresponding angles of ΔABC and ΔA′B′C′ are congruent.
Dilations preserve angle measure; therefore the corresponding angles of ΔABC and ΔA′B′C′ are congruent.

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)

do you have the measurements?
