Understanding:

[Q4] Slope intercept form is , where m is slope and b is the y-intercept. We calculated the slope in the previous question which was -45. We can find b by using any point on the previous table and replacing it's x and y values, for this example, I'm going to use (0,1080).

Now, we can rewrite the equation as follows

[Q5] To find the y-intercept we simply replace every x value with a 0,

This means the y-intercept is at .

For the x-intercept, you replace the y value with a 0 and solve for x,

This means the x-intercept is at .

Solutions:

[Q4]

[Q5] x-intercept: ; y-intercept:

[Q6] The x-intercept represents the months it takes Philip to fully pay his friend for the car. The y-intercept represents the total amount Philip had to pay his friend.

the answer is d. (1.2, -4.7) on edgn

hope this !

you didn't post any answer choices, so its not 100% clear what your teacher is looking for

however, log(15/7) is equivalent to log(15) - log(7)

i'm using the rule log(x/y) = log(x) - log(y)
