Set up an equation to solve.
70% of original price equals $550, the amount Susan is paying.
0.70x = 550
Answer:
y =
x + 4
Step-by-step explanation:
The equation of a line in slope- intercept form is
y = mx + c
Given
- 3x + 4y = 16 ( add 3x to both sides )
4y = 3x + 16 ( divide all terms by 4 )
y =
x + 4 ← in slope- intercept form
Answer: The slope is -6/5
