Question

5 Find the oquation of an straight line which makes x and y intercept S (-2,-5) ​

Answer 1

Step-by-step explanation:

The X and Y intercepts of a straight line are 22 and −5−5 respectively. What is the equation of the straight line?

The X and Y intercepts of a straight line are 22 and −5−5 respectively.

⇒⇒ The coordinates of the points where the line crosses the X and Y axes are (2,0)(2,0)and (0,−5)(0,−5) respectively.

Thus we get two points lying on the line.

The two point formula for a straight line is y−y1x−x1=y2−y1x2−x1.y−y1x−x1=y2−y1x2−x1.

⇒y−0x−2=−5−00−2⇒yx−2=52.⇒y−0x−2=−5−00−2⇒yx−2=52.

⇒2y=5x−10⇒2y=5x−10

⇒⇒ The equation of the straight line is 5x−2y=10.
