Answer:
y = -1x + 6 or y = -x + 6
Step-by-step explanation:
First, let's identify what slope-intercept form is.
y = mx + b
m is the slope. b is the y-intercept.
We know the slope is -1, so m = -1. Plug this into our standard equation.
y = -1x + b
To find b, we want to plug in a value that we know is on this line: (2, 4). Plug in the x and y values into the x and y of the standard equation.
4 = -1(2) + b
To find b, multiply the slope and the input of x(2)
4 = -2 + b
Now, add 2 from both sides to isolate b.
6 = b
Plug this into your standard equation.
y = -1x + 6
This is your equation.
Check this by plugging in the point again.
y = -1x + 6
4 = -1(2) + 6
4 = -2 + 6
4 = 4
Your equation is correct.
Hope this helps!
Answer:

Step-by-step explanation:
8 HRS effort: $9 x 8 = $72
12.5% commission of $380: $380 x 0.25 = $47.5
He earn : $72 + $ 47.5 = $119.5
10x-1/-16x48 It will be 10 times negative 1 over negative 16 times 48
Answer:
x=2.5
y= -7
Step-by-step explanation:
1.)make y the subject of any equation
4x-y=17
-y=17 -4x
y = -17 + 4x
2.)substitute it in the next equation
-2x + 3(-17 + 4x)= -26
-2x -51 + 12x = -26
-2x + 12x - 51= -26
10x -51= -26
10x = 25
x = 2.5
3.) substitute the x- value into any equation
4x -y = 17
4(2.5)- y = 17
10 - y =17
-y = 7
y = -7
