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

3x - y - 7 = 0

x - 3y + 7 = 0

x - 3y - 7 = 0

x - 3y - 7 = 0

Step-by-step explanation:

We can first write this equation in Point Slope form, and then rearrange it to general form.

Note: the given point is (h,k)

Slope is m.

The equation is:

y-k=m(x-h)

Therefore, the equation in point slope form would be:

y+2=1/3(x-1)

Now, we can change that to general form.

y+2=1/3x-1/3

1/3x-1/3-y-2=0

1/3x-y-2 1/3=0

Multiply everything by 3.

x-3y-7=0

Therefore, the corrrect answer is option 3.

step-by-step explanation:

f(x)=2x^2 -1 

translation is a function transformation that transform the function in a way of translating. by translating the function its graph is moved  up an down. moving the function f(x) 2 units to the left will be the new function g(x) with the equation: g(x)=f(x+2)=2(x+2)^2 -1
