Question

. The following chart shows the number of concert tickets sold and the profit earned. Find the slope of the line through these points

Tickets Sold Profit (dollars)
50 100
100 250
150 400
200 550

Answer 1

the slope of the line through these points is 3

Explanation:

Given that:

#Tickets #Sold Profit (dollars)

50 100

100 250

150 400

200 550

Find the slope of the line through these points

As we know, the slope of a linear line can be calculated as following:

m = Δy / Δx , where:

• Δy = y2 - y1
• Δx = x2 -x1

In this situation,

• let the point (50 100) is (x1, y1),
• let the point (100, 250) is (x2, y2),

We have the slope:

m = (250 -100) / (100 -50) = 150 / 50 = 3

So the slope of the line through these points is 3
