Using slope-intercept form
y=mx+b
y being the y value of a co-ordinate
x being the x value of a c-ordinate
m being the slope
b being the y intercept
You've been given slope of 1
and point (0,2) is the yintercept
Hence
y= x +2
Or USE ALGEBRA
IT"S SUPER FUN!!!!
x=0
y=2
m=1
b=?
y=mx+b
2=1(0)+b
b=2
Hence
y=x+4

Answer:
Solution-
We know that,
Residual value = Given value - Predicted value
The table for residual values is shown below,
Plotting a graph, by taking the residual values on ordinate and values of given x on abscissa, a random pattern is obtained where the points are evenly distributed about x-axis.
We know that,
If the points in a residual plot are randomly dispersed around the horizontal or x-axis, a linear regression model is appropriate for the data. Otherwise, a non-linear model is more appropriate.
As, in this case the points are distributed randomly around x-axis, so the residual plot show that the line of regression is best fit for the data set.
Hope this helps!
Step-by-step explanation:
$1,240-$150-$244-$300-$50=$496 left
496/1240=x/100
x=49600/1240=40%
All you have to do is use proportions.
