Question

The equation of a line with x-intercept 7 and y-intercept −7 is ______.

विकल्प

• x − y = 7

• y − x = 7

• x + y +7 = 0

• x + y = 7

Answer 1

The equation of a line with x-intercept 7 and y-intercept −7 is x − y = 7.

Explanation:

By intercept form,

Equation of line: `x/a + y/b = 1`

Given,

x-intercept (a): 7

y-intercept (b): −7

Substituting values in equation, we get:

⇒ `x/7 ​+ y/(−7) = 1`

⇒ `x/7 - y/7 = 1`

⇒ x − y = 7
