Question

Select the correct answer.

Which statement is true about the graph of this equation?

y + 4 = 4(x + 1)

A.
The graph is a line that goes through the points (1,-4) and (0,0).
B.
The graph is a line that goes through the points (1,4) and (2,8).
C.
The graph is a line that goes through the points (-4,-1) and (-3,-3).
D.
The graph is a line that goes through the points (4,1) and (5,5).

Answer 1

Y + 4 = 4(x+1)
Bringing the equation to a slope intercept form
Y + 4 = 4x+4
Y = 4x + 4 - 4
Y = 4x
In the answer B the points (1,4) and (2,8) are on the line as y(1) = 4 * 1
y(1) = 4
And y(2) = 4 * 2
y(2) = 8
So the answer is B
