What is the slope of a line parallel to the equation 4x - 2y =8
Ksju [112]

4x − 2y = 8, 2y = 4x − 8 and y = 2x − 4. In this form, we can see that the slope of the line is 2 and the y-intercept is −4 (which means the point (0,−4)). The slope of any line that is perpendicular to this one is the negative reciprocal of the slope of this line or −1/2.

Salutations!

When we are moving towards the right, the power will always be negative. If we are moving towards the left the power will always be positive. So the question shows the decimal point after zero.. which means we have to move the point infront of 8. We are moving to the right side, and therefore the power would be negative.

8.235*10^{-4}

Hope I helped (:

A regular hexagon is rotated 360° about its center. How many times does the image of the hexagon coincide with the pre image dur
lianna [129]

The image of the regular hexagon coincides with the pre-image 6 times during rotation.

A regular hexagon is a polygon that has six equal sides and six equal angles.

In a single rotation which is usually the rotation of an object at 360°, the number of times in which the regular hexagon coincides with its pre-image is 6 times, this is because it has 6 equal sides and 6 equal angles.
