<u><em>Definition of: Coefficient</em></u>
A number used to multiply a variable.
<u><em>Example:</em></u> 6z means 6 times z, and "z" is a variable, so 6 is a coefficient.
Variables with no number have a coefficient of 1.
<u><em>Example</em></u>: x is really 1x.
<em><u>coefficients:</u></em>
3<em>x⁴</em>+ 5<em>x²</em> + 1<em>x</em>
<u><em>sum of the coefficients:</em></u>
3 + 5 + 1
8 + 1

Answer:
y-intercept: (0, 5); slope: 1/4
Step-by-step explanation:
The slope (m) is found from ...
m = (y2 -y1)/(x2 -x1)
Using the first two points in the table, this is ...
m = (8 -6)/(12 -4) = 2/8 = 1/4 . . . . . eliminates choices A and C
__
Then, the point-slope form of the equation of the line can be written as ...
y -y1 = m(x -x1)
y -6 = (1/4)(x -4) . . . fill in known values
y = 1/4x -1 +6 . . . . . add 6
y = 1/4x +5
Then the value of y when x=0 is ...
y = 0 +5 = 5
So, the y-intercept is (0, 5) and the slope is 1/4, matching the last choice.
