Answer:
The equation would be:
y= 4,000(x-1)+20,000
y= annual income
x= number of years
With this you can find the points for the scatter plot:
x=1 y= 20,000
x=2 y= 24,000
x=3 y= 28,000
x=4 y= 32,000
x=5 y= 36,000
x=6 y= 40,000
x=7 y= 44,000
x=8 y= 48,000
The scatter plot that represents this situation is attached.
Given coordinates (1,3) and (0,1).
In order to find the equation of line, we need to find the slope between given coordinates.
We know slope formula,
m=
We have (x1,y1) = (1,3) and (x2,y2) = (0,1).
Plugging values of x1,y1,x2 and y2 in slope formula, we get
Simplifying top and bottom of the fraction we got for slope
We got slope m=2.
We are given second point (0,1), where x-coordinate is 0 and y-coordinate is 1.
y-intercept is a point on y-axis, where x=0.
Therefore, y-intercept = 1.
Now, applying slope-intercept form of the linear equation
y=mx+b, where m is the slope and b is y-intercept.
m=2 and b=1.
Plugging values of m and b in slope-intercept form, we get
y=2x+1.
Therefore, point-slope form for the line is y=2x+1.
