EXPLANATION.
Linear equation,
⇒ 2x - 3y = - 15.
As we know that,
Put the value of x = 0 in equation, we get.
⇒ 2(0) - 3y = -15.
⇒ - 3y = - 15.
⇒ 3y = 15.
⇒ y = 5.
Their Co-ordinates = (0,5).
Put the value of y = 0 in equation, we get.
⇒ 2x - 3(0) = - 15.
⇒ 2x = - 15.
⇒ x = -15/2.
⇒ x = -7.5.
Their Co-ordinates = (-7.5,0)
Linear equation cuts the x-axes at (-7.5,0).

Given,
- Linear Equation = 2x -3y = -15
To Find,
- At what point the graph of the linear equation 2x - 3y = - 15 cuts the x-axis.
Solution,
We know that,
The Linear Equation cuts x-axis.
When,
y co-ordinate is 0.
If y = 0,
→ 2x -3y = -15
→ 2x - 3(0) = -15
→ 2x - 0 = -15
→ 2x = -15
→ x = -15/2
→ x = -7.5
Required Answer,
At (-7.5,0)
Linear equation
2x - 3y = - 15
cuts the x-axis.
