(2x + 4y = 14) \div 2 = x + 2y = 7
making x the subject
x = 7 - 2y
substitute into second equation
3(7 - 2y) + 12y = 51
by solving, y=5

substitute into first equation
2x + 4(5) = 14
by solving, x=-3

Therefore the ordered pair is (-3,5)

Which graph matches the equation y+3=2(x+3)?
Vlad1618 [11]

Answer:

The graph that includes points (-3,-3) and (0,3)

Step-by-step explanation:

In the pictures attached, the options are shown.

The equation:

y+3=2(x+3)

has the point-slope form, which is:

y-y₁=m(x-x₁)

where (x₁, y₁) is a point on the line and <em>m</em> is its slope. This means that (-3,-3) is on the line. To know the y-intercept of the line, we have to replace x = 0 into the equation, as follows:

y+3=2(0+3)

y+3 = 6

y = 6 - 3

y = 3

Then, point (0, 3) is on the line.
