Answer:
slope = -3/2
y-int = 3
Step-by-step explanation:
3x + 2y = 6
-3x -3x
2y = -3x +6
/2 /2 /2
y = -3/2 + 3
In standard form it would be 2x - 3y = 3
Answer:
4
Step-by-step explanation:
40-36=4
- Slope Formula:
So remember that <u>perpendicular lines have slopes that are negative reciprocals to each other</u> and <u>parallel lines have the same slope.</u> To find out if they are either parallel or perpendicular, plug the pair of points into the slope formula to find their slopes:
Since these slopes aren't the same nor are they negative reciprocals to each other, <u>the lines are neither parallel nor perpendicular.</u>
So first you have x, number of hot dogs, and y, the number of hamburgers. You need to add x to y to find 230, which is the total amount of hot dogs and hamburgers sold. Then you add 0.50x to 0.75y, which equals $138.50
Your answer is x + y = 230 and 0.50x + 075y = 138.50.
