Answer:
y = 1/3x - 17/3
Explanation:
Slope intercept form is written in the form y = mx + c, where m is the gradient and c is the y intercept. This question is set out in a bit of a confusing way, but I think we can assume that the line passes through the point (5, -4), and has a gradient of 1/3. Hence, we can write the equation as:
y = 1/3x + c
Now, to find c, we can input the x and y co-ordinates from the given point, so that we are solving for only one unknown. Hence:
-4 = 1/3(5) + c
c = -4 - 5/3
c = -12/3 - 5/3
c = -17/3
Hence, the final equation is:
y = 1/3x - 17/3
Hope that helps!
