What is the gradient of the line 3y=2x-6

Mathematics

Karo-lina-s [1.5K]3 years ago

Answer:

2/3

Step-by-step explanation:

The gradient of any line in standard form, Ax + By = C is -A/B.

Divide each term by 3 and simplify.

3y = 2x - 6

3y / 3 = y

2x / 3 = 2/3x

6 / 3 = 2

So, y = 2 / 3 x - 2

slope or gradient = 2/3

Explanation:

The first step in finding the slope of a line that is written in standard form is to write the equation in slope-intercept form, y=mx+b. To do this, rearrange the variables. The standard form, Ax + By = C can be rewritten as By = -Ax + C.

Divide by B to simplify  

In the equation By = -Ax + C, B needs to be distributed through the equation. To do this, divide both sides by B. The answer is y = (-A/B)x + C/B.  

Find the slope

Once the equation of the line is in slope-intercept form and is simplified, then the slope equals the term in front of the x variable. In the standard form from step 2, the slope is -A/B.

You spin the spinner once.
MAVERICK [17]

Answer:

50%

Step-by-step explanation:

The P(even or divisor of 28) = P(even) + P(divisor of 28) - P(even and divisor of 28). The P(even) = 2/4 = 1/2. The P(divisor of 28) = 2/4 = 1/2. The P(even and divisor of 28) = 2/4 = 1/2 as 2,4 are even numbers and divisors of 28.

1/2 + 1/2 - 1/2 = 1/2 = 50%

Suppose y varies directly with x write a direct variation equation that relates x and y
gogolik [260]

Answer:

Option D

Y=2.6x

Step-by-step explanation:

When y=10.4 and x=4, these two can be related by the equation

10.4=4x

Making x the subject of the formula then x=10.4/4=2.6

Relating x and y then we have the equation

Y=2.6x

For example, when x is 4 then y=2.6x=2.6(4)=10.4 as given in the question. Therefore, the right option is D

Y=2.6x
