The equation is y= 1.5x+38.5 and the value of y-intercept is 38.5
What is slope and y-intercept?
- The values of the slope and y-intercept reveal details of the relationship between the two variables, x and y.
- The slope shows how quickly y changes for every unit change in x. When the x-value is 0, the y-intercept shows the y-value.
Standard form of a slope intercept form is
y= mx+c
here m is slope. This is rate of y increases as x increases by 1,
C is y intercept, this is the value of y at start(when x=0).
Here y is amount collected. Here we have 38.5 at start. So C= 38.5
In each week amount (y) increases by 1.5. So m=1.5
Substitute in the standard form: Then,
y= 1.5x+38.5
Hence, the equation is y= 1.5x+38.5 and the value of y-intercept is 38.5
