Question

the equation of a line passing through a point (1,1) and having slope "-3" unit is____
​

Answer 1

Answer:

"A general equation for line having slope m is , y = mx + c , where m is slope of line .

Here m = 3,

So, y = 3x + c .

Now to eliminate c we will use the information that line passes through (1,2),

2 = 3(1)+c which gives c = -1 .

So equation of line is , 3x - y - 1 = 0 . "

Answer 2

Answer:

"A general equation for line having slope m is , y = mx + c , where m is slope of line .

Here m = 3,

So, y = 3x + c .

Now to eliminate c we will use the information that line passes through (1,2),

2 = 3(1)+c which gives c = -1 .

So equation of line is , 3x - y - 1 = 0 . "
