Y-intercept = -13
x-intercept = 2.6 or 2 3/5
-13 is the y-intercept. In the equation, y=mx+b, b is the y-intercept. Looking at the equation, y=5x-13, we can see that -13 is in the place of b, therefore -13 is the y-intercept.
() is the x-intercept. To find the x-intercept, you need to replace values into the equation. Since the coordinates for the x-intercept consist of y being 0, you must replace y in the equation. with 0.
0=5x-13
Get rid of the -13 by adding it onto both sides. -13 is negative and the opposite of a negative is positive, thus making you add to get rid of -13.
0=5x-13
+13 +13
13=5x
Now you divide 5 from both sides to get rid of 5. The opposite of multiplication is division, so you must divide the 5 from 5x to isolate the x.
13/5=5x/5
2.6 or 2 3/5=x
Therefore the coordinates (2.6,0) represent the x-intercept, or just 2.6.
I hope this helped.
Answer:
A
Step-by-step explanation:
Plug in values
We know that x=4 and y= -8
just plug in numbers until one is correct
4-4(-8)=36
4+32=36
36=36
the answer is A
1) True. In a function, each x value has exactly one y value.
2) False. For example
is a function, but is not linear. It is represented by a parabola.
Answer: 3x - 9
Step-by-step-explanation: To solve the expression (8x – 2) – (5х – 7) we will be using properties of operations. First, use the commutative and associative properties to move the values next to each other to combine like terms.
(8x – 2) – (5х – 7)
(8x-5x)+(-2-7)
3x-9
So, the subtracted answer is 3x - 9
