What is the slope of the graph of 14x + 7y = –9?

Vera_Pavlovna [14]

We will put ur equation in y = mx + b form, and the slope will be in the m position.

14x + 7y = -9
7y = -14x - 9
y = (-14/7)x - 9/7
y = -2x - 9/7

y = mx + b
y = -2x + (-9/7)....as u can see, the -2 is in the m position and is therefore the slope.

The grid shows figure Q and its image figure Q' after a transformation: Figure Q is a pentagon drawn on a 4 quadrant grid with v

kumpel [21]

Check the picture.

we notice that for every pair (x, y) in Q, there is a point (-y, x) in Q',

this means that the transformation is a 90° counterclockwise rotation around the origin.

The transformation can be also noticed by sight in the figure.

Answer: 90° counterclockwise rotation
