Answer 1

Answer:

The equation of line passing through point (3 , 10) with slope 2 is y = 2 x + 4 .

Step-by-step explanation:

Given as :

The slope of a line = m = 2

The line is passing through point =  ,   = 3 , 10

Now, Equation of line in point- slope form

y -   = m × (x - )

Or, y - 10 = 2 × (x - 3)

Or, y - 10 = 2 × x - 2 × 3

Or, y - 10 = 2 x - 6

Or, y = 2 x - 6 + 10

Or, y = 2 x + 4

So, The equation of line  y = 2 x + 4

Hence, The equation of line passing through point (3 , 10) with slope 2 is y = 2 x + 4 . Answer
