Find the slope of a line parallel to 3x + y = 15

Rearranging the equation gives us y=15-3x

if we were to find an equation for a PARALLEL line, we would just use the same slope.

if we were to find an equation for a PERPENDICULAR line, we would do the opposite reciprocal. in this case, that would be answer D. but this is WRONG!

the question asks us to find the slope of a PARALLEL line. thus, the answer is C.

final answer -- C.

A scale drawing of a building has the scale 0.5in : 6ft. A wall is 30 ft long. How long will the wall be on the drawing?
g100num [7]
The scale 0.5 in : 6 ft, means that

any distance of 0.5 in on paper, represents 6 ft in reality


for example:
 
0.5*2= 1(in) represents 6*2=12 (ft)

0.5*4= 2(in) represents 6*4=24 (ft) 

0.5*10=5(in) represents 6*10=60 (ft) and so on...


Let the wall be x (in) in the drawing:

0.5 (in) represents 6 (ft),
 x (in) represents 30 (ft)
----------------------------------------

thus x = (0.5*30)/6 = 15/6= 2.5 (in)


Answer: 2.5 in

KonstantinChe [14]

Answer:

In this graph, the y-intercept of the line is -2, if the coordinates are needed, its (0,-2). The equation of the line is y= x-2 ( slope intercept form ).

Step-by-step explanation: I am not sure how to use the multiplication system below to write the equation, so sorry I couldn't help!
