Write an equation of the line that is parallel to y = 1/2x + 3 and passes through the point (10, -5).

bearhunter [10]

y = mx + b

"m" is the slope, "b" is the y-intercept (the y value when x = 0)

You need to find "m" and "b"

For lines to be parallel, the slopes have to be the same.

The given line's slope is 1/2, so the parallel line's slope is also 1/2.

y = 1/2x + b

To find "b", you can plug in the point (10, -5) into the equation.

y = 1/2x + b

-5 = 1/2(10) + b

-5 = 5 + b Subtract 5 on both sides to get "b" by itself

-10 = b

y = 1/2x - 10 Your answer is D (you could have just found the slope to get your answer, since all the slopes are different)

Help with functions right quick? :) please

-Dominant- [34]

The answer is: [B]: -4 .
_____________________________
Here is the problem:
_____________________
"Find f(3)."
_______________________
f(x) = $\left \{ {x + 5 ; if x \ \textless \ -2 ; \atop {-4; if x \geq -2 ;}} \right.$ ;
______________________________________
Since we are asked to find: " f(3)" ; we consider the number, "3", which is GREATER THAN OR EQUAL TO "-2" ; (that is, " 3 $\geq$ -2" ;
and f(x) = -4 if x $\geq$ -2 .
_____________________________________________________
So, in this case, f(x) = f(3) = -4 ; which is: "Answer choice: [B] ".
