Answer:
y = 3x + 2
y = 6x – 3
y = 2/3x + 6
y = –1/3x – 4
y = 2x + 1
Correct answer:
y = 3x + 2
Explanation:
Convert the equation to slope intercept form to get y = –1/3x + 2. The old slope is –1/3 and the new slope is 3. Perpendicular slopes must be opposite reciprocals of each other: m1 * m2 = –1
With the new slope, use the slope intercept form and the point to calculate the intercept: y = mx + b or 5 = 3(1) + b, so b = 2
So y = 3x + 2
200% bc it went up 2x as much as it cost before
Answer:
Step-by-step explanation:
Its given:
Include a picture of a hw problem or include how much money he has right now. This is not solveable.
To write 0.1 as a percentage you have to multiply it by 100 and then put the % sign at the end of it.
0.1 X 100 = 10%
