Question

What is the equation of the line that contains the point (-1, 4) and has a slope of 3?

Answer 1

Option 3 y=3x+7 is correct

Answer 2

Let's write the equation with formula:-

$\boxed{ \sf \: formula : y -y_{1} = m(x - x_{1})}$

Where,

• x1 is -1 and y1 is 4 and m is 3

$\tt \: y - 4= 3(x - ( - 1))$

$\tt \: y - 4 = 3(x + 1)$

$\tt \: y - 4 = 3x + 3$

$\tt \: y = 3x + 3 + 4$

$\tt \: y = 3x + 7$

Thus, The correct choice is option C!!~
