Answer:
y= 
x-
Step-by-step explanation:
The first step to making an equation of a line is finding the slope. To do this, we can use the point slope formula: 
In this case,
y2=1
y1= -2
x2=5
x1= -4
plug this into the formula: 
, which gives us 3/9, or 1/3 as the slope.
Now we have the equation y=1/3x+b. Let's find b! We can do this by plugging in one of the points into our new equation, let's use (5,1)
1=y, 5=x
1=(5)+b
b= -
now, we plug b= -2/3 into our equation, and we finally get y= x-
The answer ti the question is. c
Answers + Explanation:
1. x + 7 =10
if you know some number + 7 is 10, you know that number must be 3.
so, x = 3
the other way you can solve this would be:
x + 7 = 10
subtract 7 from both sides of the equation
x + 7 - 7 = 10 - 7
x = 3
2. Use the same strategy:
x - 8 = -5
add 8 to both sides of the equation
x - 8 + 8 = -5 + 8
x = 3
3. x + 3 = 6
subtract 3 from both sides of the equation
x + 3 - 3 = 6 - 3
x = 3
4. x + 6 = 3
subtract 6 from both sides of the equation
x + 6 - 6 = 3 - 6
x = -3
Answer:
x = 14/9
Step-by-step explanation:
70 - 8x = 56 + x
- 8x - x = 56 - 70
- 9x = - 14
- x = - 14/9
x = 14/9
