I am having tuble with this problem:
Graph the line given by the formula y=2x+3. Using the graph, find:
The value of y corresponding to the value of x equal to −1; 2; 3; 5
I don't really know how to find the answer can you guys give me the answer and explain how you got it
Thanks so much
:)
I also have another question:
Write the equation of the line parallel to the given line and passing through the given point.
y=6 through (3,4)
this is what i did and i got it wrong
4=24+b
-20=b
y=6+(-20)
i did the same way of solving for this problem
y=x+5 through (8,1)
1=8+b
b=-7
y=x+(-7)
and it's correct
sory typo in top
this is what i did and i got it wrong
y=2x+3.
y(-1) = 2(-1)+2 = -2+3 = 1
y(1) = 2(1)+3 = 2+3 = 5
and so on
The line y=6 is a horizontal line.
A horizontal line through (3,4) is y=4
Sure, I'd be happy to help you with this problem! To find the value of y corresponding to different values of x on a graph, you need to substitute the given values of x into the equation y=2x+3.
Let's start by finding the value of y when x=-1. Substitute x=-1 into the equation:
y = 2(-1) + 3
y = -2 + 3
y = 1
Therefore, when x is equal to -1, the corresponding value of y is 1.
Next, let's find the value of y when x=2:
y = 2(2) + 3
y = 4 + 3
y = 7
Hence, when x equals 2, the corresponding value of y is 7.
Now, let's move on to finding the value of y when x=3:
y = 2(3) + 3
y = 6 + 3
y = 9
Therefore, when x is equal to 3, the corresponding value of y is 9.
Finally, let's find the value of y when x=5:
y = 2(5) + 3
y = 10 + 3
y = 13
Hence, when x equals 5, the corresponding value of y is 13.
To summarize, substituting x = -1, 2, 3, and 5 into the equation y=2x+3 gives the corresponding values of y as 1, 7, 9, and 13 respectively.
