Answer:
\[y=-5x+18\]
Step-by-step explanation:
Given that the line is parallel to \[y = -5x + 6\]
Hence the slope of the line is given by -5
Hence the equation of the required line can be represented by \[y = -5x + c\]
This line passes through (4,-2). Substituting:
\[-2 = -5 * 4 + c\]
=> \[-2 = -20 + c\]
=> c = 20-2 = 18
So the required equation of the line is given by : \[y = -5x + 18\]
From the given options, option 3 is the correct one.
Answer:
A
Step-by-step explanation:
It isn’t because if you do the vertical line test and try to put vertical lines all throughout the graph, two dots will touch the same line.
Find the x intercepts by setting each x to equal 0:
(4-x)=0
4 -4 = 0
First x intercept = (4,0)
(x+2) = 0
-2 + 2 = 0
Second x intercept = (-2,0)
Now find the Y intercept by setting the x's to 0 and solve for y:
y = (4-0)(0+2)
y = 4*2
y = 8
The Y intercept is (0,8)
Now find the graph the the parabola crosses the x axis at -2 and 4 and also crosses the Y axis at 8.
Graph A is the correct one.
