Learn Intercept Group

Introduction for learn intercept group:

The intercept group has different types, one is x intercept and second one is y intercept and last one is z intercept. X intercept means point crosses the x axis and y intercept means point crosses the y axis of the line. When x = 0 and y= 0 that intercept is called as z intercept. Let us learn about the intercept group example problems and practice problems are given below.

Learn intercept group example problems:


Example 1: Find the x intercept of the line, 2.5x + 5y = 20

Solution:

The slope intercept form is y = mx + b, where m is the slope of the line.

Given equation is in the form of ax + by = c. To find the x- intercept Plug y = 0 in the equation

Here x intercept, so y = 0

2.5x + 5(0) =20

2.5x = 20

Divide by 2.5 on both sides.

` (2.5x)/(2.5)` = ` (20)/(2.5)`

After simplify this, we get

x = 8

x intercept = 8

Example 2: Find the y intercept of the line, 12x + 6.5y = 45.5

Solution:

The slope intercept form is y = mx + b, where m is the slope of the line.

Given equation is in the form of ax + by = c. To find the y- intercept Plug x = 0 in the equation

Here y intercept, so x = 0

12(0) + 6.5y = 45.5

0 + 6.5y = 45.5

6.5y = 45.5

Divide by 6.5 on both sides.

`(6.5y)/(6.5)` = ` (45.5)/(6.5)`

After finding this, we get

y = 7

y intercept = 7

Example 3: Solve the z intercept of the given equation: 0.5x - 1.5y + 3.5z = 35

Solution:

The given equation is 0.5x - 1.5y + 3.5z = 35. Let us find z intercept.

Substitute x = 0 and y = 0

0.5(0) - 1.5(0) + 3.5z = 35

0 - 0 + 3.5z = 35

After simplify this, we get

3.5z = 35

Divided 3.5 on both sides, we get

`(3.5z)/(3.5)` = `(35)/(3.5)`

After simplify this, we get

z intercept = 10

These example problems are very helpful to learn of intercept group.


Learn intercept group practice problems:


Problem 1: Find the x intercept of the line, 2.5x + 1.5y = 40

Answer: x intercept = 16

Problem 2: Find the y intercept of the line, 5x + 14.5y = 58

Answer: y intercept = 4

Problem 3: Solve the z intercept of the given equation: 6x - 4y + 125z = 250

Answer: z intercept = 2
