Answer:

The slope of the line perpendicular to 8x - 6y = -4 = -3/4

All lines parallel to y = 4x/ 3 - 2/3 have thesame slope of 4/3

Step-by-step explanation:

To find the slope of a line Parallel or perpendicular to another, we should bear in mind that:

When two lines are parallel, they have an equal slope.

Also, when two lines are perpendicular, they have opposite signs and they are reciprocals of each other.

From the question:

8x - 6y = -4

Let's rearrange the equation to have in the form of:

y = mx + c.

Where m= slope

C = intercept.

Therefore, for PERPENDICULAR

6y = 8x - 4.

y = 8x/6 - 4/6

y = 4x/3 - 2/3

SLOPE = 4/3

To get tge slope perpendicular to the line y = 4x/3 - 2/3;

Lets get the reciprocal and the opposite sign.

Slope = 4/3

Perpendicular slope = - 1/ m

= -3/4

Therefore, the slope of the line perpendicular to = -3/4

PARALLEL:

6y = 8x - 4.

y = 8x/ 6 - 4/6

y = 4x/ 3 - 2/3

SLOPE = 4/3.

Therefore, all lines parallel to y = 4x/ 3 - 2/3 have thesame slope of 4/3

Which representation of a transformation on a coordinate grid preserves congruence?
Zepler [3.9K]

Answer:

Rotations, reflections and translations.

Step-by-step explanation:

Rotations, reflections and translations are transformations that preserve the both the angle measurements and the lengths of the sides, so congruence is preserved.

Dilations are transformations that keep the angle measurements, but the side lengths change, so the transformation is similar, not congruent.
