Answer:
Gold is LESS expensive than platinym because SLOPE of graph is LESS
SLOPE gives UNIT DOLLARS PER OUNCE.
Step-by-step explanation:
sorry im late
X^2 + 3x - 2 - (2x^2 - x + 6) =
x^2 + 3x - 2 - 2x^2 + x - 6 =
-x^2 + 4x - 8 <===
To find the equation of a trend line, It is important to find the X axis and Y axis, Once x axis and y axis is found if there is an association between x axis and y axis, We use linear equation to produce the trend line. Linear regression or algorithm called as OLS (Ordinary least square). Y= mx +c
y = dependent variable, x = independent variable , constant = c , m = y2-y1/x2-x1.
Step-by-step explanation:
- Scatter plot is to find association of two different variable.
- Trend line is the equation between xaxis and y axis.
- Prediction is best way to form equation.
- Linear regression y=mx +c
- Equation helps in predictive modelling between next best form.
- Y is a dependent variable or example sales.
- X can be n number of variable involved in the association rule.
- Linear regression is starting phase of data analysis.
- C = constant there is a certain point, where system has been started.
- Stock market did not start from 0 it started at a certain point.
Answer:
y = 1/3 x + 2
Step-by-step explanation:
We see points (-3, 1) and (3, 3).
We also see point (0, 2), the y-intercept.
To go from (-3, 1) to (3, 3), go up 2 and right 6.
slope = m = rise/run = 2/6 = 1/3
y = mx + b
y = 1/3 x + 2
