A line has an equation of a form,
From a graph we can pick two points on the line, say A and B where,
Using their coordinates we are able to calculate slope.
Hence,
The x and y terms can be replaced with coordinates of one point either A or B. I'll pick A.
And now solve for b.
Hence,
Simply,
Hope this helps.

Answer
D. `(y+4) = (5)/(3)(x+ 1)`
Step by step explanation
The given points are (-1, -4) and (2, 1)
Slope = (y2 - y1)/(x2 - x1)
= (1 - (-4)) / (2 - (-1))
= (1 + 4) / (2 +1)
m = 5/3
When two points are given, the equation of the line is
(y - y1) = m (x - x1)
y -(-4) = 5/3 (x - (-1))
y + 4 = 5/3 (x + 1)
The answer is (y+4) = (5)/(3)(x+ 1)
Thank you.
The decrease in the value of the toy is $9.25 if you subtract $ 0.75 from $10.00 then you get $9.25 so it's $9.25 cheaper
5. since .6 is greater than 5, we round up.
