Question

What is the equation of a line, in general form, that passes through point (1, -2) and has a slope of 1/3. 1.x - 3 y - 7 = 2.x - 3 y + 7 = 0 3. 3 x - y - 7 = 0

Answer 1

Answer:

x- 3y - 7=0

Step-by-step explanation:

the line in the slope-intercept form:

• y= mx+b

m= 1/3 and point given (1, -2) by using which we find y-intercept:

• b= y-1/3x
• b= -2- 1/3*1= - 7/3

• y= 1/3x- 7/3

General form of a line is: ax+by+c= 0

converting:

• y= 1/3x- 7/3  ⇒  3y= x- 7  ⇒  x- 3y - 7=0
