Answer with explanation:</h2>
When there is a linear relationship is observed between the variables, we use linear regression predict the relationship between them.
Also, we predict the values for dependent variable by modelling a linear model that best fits the data by drawing a line Y=a+bX, where X is the explanatory variable and Y is the dependent variable.
In other words: The line of best fit is a line through a scatter plot of data points that best describes the relationship between them.
That's why the regression line referred to as the line of best fit.
I think is 2x+y=-5 the answer
Answer:
46 euros
Step-by-step explanation:
£30 = 40 euros
4.50 = £3 and £1.50
£3 = 4 euros
1.50 = 2 euros because you half the 4 euros because half of 3 is 1.50
hope this helps if not sorry
Answer:
x^2-3x=4
x^2-3x-4=0
x^2-4x+x-4=0
x(x-4)+1(x-4)=0
(x+1)(x-4)=0
x=-1,4
x- intercepts in the point (-1,0) and (4,0)
