Solve the equation for y. Identify the slope and y-intercept then graph the equation.
viva [34]

Answer:

y = -3    m = -1     b = 3

Step-by-step explanation:

-3y=3x-9

To isolate the y variable, divide both sides by -3.

y = -1x + 3

y = -3

m = -1

b = 3

What is the equation of the line that is parallel to the line 5x + 2y = 12 and passes through the point (-2, 4)?
Zepler [3.9K]

First let’s put 5x+2y = 12 into slope-intercept form.

2y = -5x + 12

y = (-5/2)x + 6

So any line that is parallel to y = (-5/2)x + 6 must have a slope of -5/2.

Our answer then is y = (-5/2)x + c

Now all that remains is to find out the value of c.

We know this line passes through the point (-2,4). Which means when x = -2, y = 4.

4 = (-5/2)(-2) + c

4 = 5+c

c = -1

Hence the line you want is y = (-5/2)x - 1

Since the question gave the line in standard form and didn’t ask for any particular form, let’s give the answer in the same form that the question asked.

2y = -5x - 2

5x + 2y = -2

Classify the pair of angles, then find the value of x.<br> (PLEASE HELP ME OUT!!)
Leona [35]

Answer:

X = 55°

Step-by-step explanation:

You can tell if a pair of angles, in this case, is 90° if you see the red box in the corner of the angle.

The pair of angles in the picture are complementary angles, which add up to 90°. Therefore, subtract 35 from 90 to find the value of X which is 55°.

Hope this helped! <3
