Given:
The slope of the line is 3.
The line passes through the point (2,-1).
To find:
The equation of the line.
Solution:
Point slope form of a line: If a line passes through the point with slope m, then the equation of the line is
The line passes through the point (2,-1) with slope 3. So, the equation of the line is
Therefore, the required equation is . Hence, all the options are incorrect.
The definite value for p is 9.
But how are 8, 7, or 6 the value of p?
I personally think that you should contact the teacher who made this question. He/She probably meant to say What IS the value for p?
You use algebra to get the value for p:
20p-45 = 9p + 5p
Start solving from there.
After sale, the price is $135
75% is $135
so 100%
(135/75) * 100
(135/3) * 4
45 * 4
$ 180
The medical researcher's expectation is wrong. There is enough statistical evidence to prove that 25% or more are smokers in the university.
