Write an equation for the line that is parallel to the given line and passes through the given point

Evgesh-ka [11]

Answer:

y = 2x + 2

Step-by-step explanation:

The equation ofa line in slope- intercept form is

y = mx + c ( m is the slope and c the y- intercept )

y = 2x + 4 ← is in slope- intercept form

with m = 2

Parallel lines have equal slopes , thus

y = 2x + c ← is the partial equation

To find c substitute (3, 8) into the partial equation

8 = 6 + c ⇒ c = 8 - 6 = 2

y = 2x + 2 ← equation of parallel line

Place the indicated product in the proper location on the grid (x+y+3)(x+y-4)

pashok25 [27]

Solution:

we have been asked to find the product of (x+y+3)(x+y-4).

we will multiply term by term as below

$(x+y+3)(x+y-4)=x(x+y+3)+y(x+y+3)-4(x+y+3)\\\\\ (x+y+3)(x+y-4)=x^2+xy+3x+xy+y^2+3y-4x-4y-12\\\\\text{Now take the like terms together and simplify we get}\\\\(x+y+3)(x+y-4)=x^2+y^2+2xy-x-y-12\\$

Hence the the product of (x+y+3)(x+y-4) is $x^2+y^2+2xy-x-y-12$
