What is the slope of the line with equation 6x+3y=12?
max2010maxim [7]

Answer:

<h2>The slope m = -2</h2>

Step-by-step explanation:

The slope-intercept form of an equation of a line:

y=mx+b

<em>m</em><em> - slope</em>

<em>b</em><em> - y-intercept</em>

<em />

We have the equation in the standard form:

6x+3y=12

Convert to the slope intercept form:

6x+3y=12              <em>subtract 6x from both sides</em>

3y=-6x+12           <em>divide both sides by 3</em>

y=-2x+4

slope: <em>m = -2</em>

y-intercept: <em>b = 4</em>

Sergeeva-Olga [200]

Answer:

The slope also increases

Step-by-step explanation:

The slope of a function is the ratio of change in y to change in x. For an exponential function f(x) = e^x, the slope of the function is equal to the function, i.e slope = e^x.

For a function represented by y=2^x, this is an exponential function representing growth, the slope of  y=2^x is also  2^x, therefore as the value of x increases, the value of the slope also increases.

At x = 1, slope = 2^1 = 2, At x = 4, slope = 2^4 = 16.
