Warm Up 11/22/2024 Identifying the Point of Intersection

Front

These two lines intersect at _____?

Back

(4, -2)

Front

The solution (intersection point) is:

Back

(4, 3)

Front

If m=3 and b=6, what is the correct slope intercept equation?

Back

y=3x+6

Front

What is the solution?

Back

(1, -1)

Front

At a local concert hall, the owner charges $7 per ticket. The owner must pay his band $1200. Every customer receives a brochure that costs the owner $2 for each person. How many people must attend for him to breakeven?

Back

240 people

Front

What is the definition of the point of intersection?

Back

The point where two lines meet or cross each other on a graph.

Front

What is the slope-intercept form of a linear equation?

Back

y = mx + b, where m is the slope and b is the y-intercept.

Front

How do you find the slope of a line given two points (x1, y1) and (x2, y2)?

Back

Slope (m) = (y2 - y1) / (x2 - x1).

Front

What does it mean if two lines are parallel?

Back

They have the same slope and will never intersect.

Front

What does it mean if two lines are perpendicular?

Back

Their slopes are negative reciprocals of each other.
