What is the equation for the line of best fit for statistical chart?(In math)

1 answer:

5 0

The line of best fit is described by the equation ŷ = bX + a, where b is the slope of the line and a is the intercept (i.e., the value of Y when X = 0). This calculator will determine the values of b and a for a set of data comprising two variables, and estimate the value of Y for any specified value of X.

Is (0,0) a solution of the system y>x and x+y>0?

olga55 [171]

Plug the values (x,y)=(0,0) into the inequalities:

$y\ \textgreater \ x \\
0\ \textgreater \ 0 \\
not \ true \\ \\
x+y\ \textgreater \ 0 \\
0+0\ \textgreater \ 0 \\
0\ \textgreater \ 0 \\
not \ true$

0 isn't greater than 0, no (0,0) is not a solution to either of these inequalities.

The answer is D.

Which linear inequality is represented by the graph?

Dovator [93]

Answer:

The answer to your question is the second choice (y ≥ 1/3x - 1)

Step-by-step explanation:

Process

1.- Find two points of the graph

A (0, -1)

B (3, 0)

2.- Find the slope

m = (0 + 1)/(3 - 0)

m = 1/3

3.- Find the equation of the line

y - y1 = m(x - x1)

y + 1 = 1/3(x - 0)

y + 1 = 1/3x

y = 1/3x - 1

4.- Find the equation of the inequality

We need the upper part of the line so the inequality must be

y ≥ 1/3x - 1
