What is the equation in standard form of the line which passes through (1, −3) and has a slope of 2?

Question

imer · Answer

Since its linear equation, it would be
$$y−y0=m(x−x0)→y−(−3)=2(x−1)→y=2x+1$$

anonymous · Answer

But none of my answers look like that :( @imer

anonymous · Answer

2x − y = 5

 2x − y = −5

 2x + y = 5

 2x + y = −5

imer · Answer

sorry, I forgot to carry the sign, $$y−y0=m(x−x0)→y−(−3)=2(x−1)→y=2x-5$$

anonymous · Answer

Wait so wich one is it..... 2x-y=5?

imer · Answer

First one; 2x − y = 5

anonymous · Answer

Thank you!!! Can you help with another problem?

imer · Answer

Sure just post it.

anonymous · Answer

Given that f(x) = 2x + 1 and g(x) = the quantity of 3x minus 1, divided by 2, solve for g(f(3))

imer · Answer

$$f(x)=2x+1, g(x)=(\frac{ 3x-1 }{ 2 })$$$$gf(3)=\frac{ 3(2(3)+1)-1 }{ 2 }  \rightarrow \frac{ 3(6+1) -1 }{ 2 } \rightarrow \frac{ 20 }{ 2 } \rightarrow 10$$
