First you need to simplify the left side of the equation to get 2x-2 \geq -12
Then you add by two on both sides to get 2x \geq -10
Finally you divide by 2 on both sides to get x \geq -5

Determine which lines in the diagram are parallel. A) a || b B) b || c C) a || c D) b || d
spayn [35]

Line a and line c are parallel lines that are given as a || c. Then the correct option is C.

<h3>How are parallel straight lines related?</h3>

Parallel lines have the same slope since the slope is like a measure of steepness and since parallel lines are of the same steepness, thus, are of the same slope.

Since the given parallel line has equation y = 2x + 2, thus its slope is 2 and thus, the slope of the needed line is 2 too.

Then we have

The distance between line a and line c is constant. Then line a and line c are parallel lines.

Line a || line c. Then the correct option is C.

If a line with a slope of -2 crosses the y-axis at (0, 3), what is the equation of the line?
Karo-lina-s [1.5K]

Answer: Option D

y +2x = 3

Step-by-step explanation:

The equation of a line in the form of "slope-interception" has the following form:

y = mx + b

Where m is the slope of the line and b is the interception of the line with the y axis.

In this case we know that the line has a slope of -2. Then m = -2.

We also know that the line intercepts the axis y at the point (0, 3) therefore we know that:

b = 3.

Finally the equation of the line will be:

y = -2x + 3

If we add 2x on both sides of the equation we get:

y +2x = 3

The answer is the option D
