Question

Using the slope program, create the line y = 2x. Keeping the line the same, move one (or both) of the points so the triangle created by the points has a vertical length of 10 units. What is the horizontal length? Does this horizontal length match the answer you found in the previous question?

Answer 1

`\\ \sf\longmapsto y=2x`

• Vertical length=y
• Horizontal length=x

Put y=10 in equation

`\\ \sf\longmapsto 10=2x{/tex]</p><p> [tex]\\ \sf\longmapsto x=(10)/(2)`

`\\ \sf\longmapsto x=5units`

Answer 2

• x = 5 units

Explanation:

Use the proportion we have to find the horizontal length:

• y = 2x

When y = 10, the value of x is:

• 10 = 2x
• x = 10/2
• x = 5
