Answer:
Question No 4
The equation will be:
Option B is correct answer.
Question No 5
The equation will be:
Option A is correct answer.
Step-by-step explanation:
Question 4
The option equations are in slope intercept forms, so we will write equation in slope intercept form.
The general equation of slope intercept form is: where m is slope and b is y-intercept
Finding Slope:
Using the point (2,10) and (4,9) we can find slope
The formula used is:
Putting values and finding slope:
So, we get slope m = - 1/2
Finding y-intercept
Using point (2,10) and slope m =1/2 we can find y-intercept
So, equation will be:
Option B is correct answer.
Question 5
The option equations are in slope intercept forms, so we will write equation in slope intercept form.
The general equation of slope intercept form is: where m is slope and b is y-intercept
Finding Slope:
Using the point (0,4) and (4,7) from the graph we can find slope
The formula used is:
Putting values and finding slope:
So, we get slope m = 3/4
Finding y-intercept
Using point (0.4) and slope m = 3/4 we can find y-intercept
So, equation will be:
Option A is correct answer.
