Answer:

The correct option is B.

Step-by-step explanation:

The given equation is

$y=-3x$ .... (1)

The slope intercept form of a line is

$y=mx+b$ .... (2)

Where, m is slope and b is y-intercept.

From (1) and (2), we get

$m=-3,b=0$

The slope of the line is -3.

Therefore the correct option is B.

The answer to this question would be B, -3. The reason for this is because when you have an equation in slope intercept form, it would be y = mx + b. In this case your b is equal to 0 so you have only y = mx. The variable m represents the slope, which is in this case, equal to -3. Hope this helps. Please rate, leave a thanks, and mark a brainiest answer. (Not necessarily mine). Thanks, it really helps! :D

What is the slope of y=7x+2

Travka [436]

Answer: m = 7

Step-by-step explanation: This equation is written in slope-intercept form which is the same thing as y = mx + b form where m represents the slope of the line and b represents the y-intercept.

Now looking at this equation, we can see that m or the slope of the line is 7.

2/6 + 1/8 A) 11/24 B) 3/14 C) 5/24 D) 8/18

So with these two fractions you're gonna have to find the LCD (lowest common denominator) before you start adding them. With 6 and 8, the LCD is 24.

So with the numerator and denominator of $\frac{2}{6}$ multiply them by 4. It'll look like this $\frac{2}{6} * \frac{4}{4} = \frac{8}{24}$

As for $\frac{1}{8}$ , do the same except multiply by 3. It'll look like this: $\frac{1}{8} * \frac{3}{3} = \frac{3}{24}$ .

Now add the new fractions together: $\frac{8}{24} + \frac{3}{24} = \frac{11}{24}$

A is the answer
