Answer:
=6x+3y
Step-by-step explanation:
3X+3(X+Y)
Distribute:
=3X+(3)(X)+(3)(Y)
=3X+3X+3Y
Combine Like Terms:
=3x+3x+3y
=(3x+3x)+(3y)
=6x+3y
Answer:
The equation of a straight line is
-3 x+5 y=15
Step-by-step explanation:
Given x - intercept of (-5,0) and y- intercept is (0,3)
here (-5,0 ) point lie on x- axis and (0,3) this point lie on y- axis
we know that the x- intercept 'a' and y- intercept 'b' formula is

so given x - intercept a =-5 and y- intercept is b= 3
now the straight line equation is 
now simplify 

Answer:
Y=-1/2x ?
Step-by-step explanation:
There might be an y intercept. First find the slope. (Change in y over change in x) -2-1 over -1-5 then you get -3/-6. You can simplify an get -1/2. That forms an equation of y=-1/2x. That might be part of the answer. You still might need to find the y intercept, and I dont know how really. Hope this helps.
The first one is. the second is 'prime'
