What is the y-intercept of the line of best fit?
what is the slope of the line of best fit for this scatter plot?
what is the equation of the line of best fit?

y intercept: 8

slope: - 1/2

equation: y = - 1/2 * x + 8

Step-by-step explanation:

2 points choosed for best fit line  (2,7) (4,6)

y = mx +b   m: slope     b: y intercept

m = difference of y / difference of x = (6 - 7) / (4 - 2) = - 1/2

for (2, 7)    b = y - mx =7 - (-1/2) * 2 = 8

equation: y = - 1/2 x + 8

check: (4,6)       6 = (-1/2) * 4 + 8

answer is the third choice:

3x^5+4x^4+x^3+2x^2-10x-7=0

step-by-step explanation:

see attached

step-by-step explanation:

given the function as;

write the equation replacing f(x) with y

form   and fill a table containing values of y with corresponding values of x

you can take a range for   values of x as -3≤x≤3

solving for x=-3

for x=-2

repeat the same procedure to get the values of y for the remaining ,x=-1 to x=3

plot the values of y against values   of x and obtain the following graph
