Find the slope-intercept equation for the line with the indicated slope and y-intercept. slope-3; y-intercept (0,31)

Step-by-step explanation:

the general form of the slope-intercept equation is as follows:

where is the slope of the line, and is the y-intercept.

In this case we know that the slope is:

and the y-intercept is the value of when , from the given point the y-intercept is at (0, 31) so the value of y, when is , thus:

and we substitute this values in the general form of the equation:

the slope intercept equation is

answer set (b) 0.5, 3/4 80% is in order from least to greatest.  

step-by-step explanation:

in order to compare rational numbers to each other, it is much easier if they are in the same form.   typically, the best form in which to evaluate rational numbers is in decimals.   in order to convert a percent to a decimal, you would divide the given percentage by 100.   you can also accomplish the conversion by moving the decimal point over two places to the left.   for example, the decimal value of 80% is 80/100, or 0.8.   in order to convert a fraction to a decimal, you need to divide the numerator by the denominator.   for example, 3/4 is 0.75.   so, for choice (b) 0.5 3/4 (0.75), 80% (0.8) is the only choice in which the numbers are in order from least to greatest.
