Th evalope kf the line is -3
Answer:
Sorry can't help try asking someone else
Step-by-step explanation:
Multiply the bracket by 5
I used PEMDAS
P= parenthesis
E= exponents
M=multiplication
D= division
A= addition
S= subtraction
7r+2= 5(r-4)
7r+2= 5r-20
Move 5r to the left hand side . Positive 5r changes to negative 5r
7r-5r+2= 5r-5r-20
2r+2=- 20
2r+2-2= -20-2
Move positive 2 to the right hand side. Changes to negative -2
2r+2-2= -20-2
2r= -22
Divide by 2 for 2r and -22
2r/2= -22/2
r= -11
Answer is r= -11

x / x = 1
Answer:
Step-by-step explanation:
As we move from the point (2, 4) to the point (3, 6), x increases by 1 and y increases by 2. Thus the slope of the line connecting these two poins is m = rise/run = 2/1, or just 2.
Use the basic point-slope equation: y - k = m(x - h). Substitute 2 for x, 4 for y and 2 for m:
y - 4 = 2(x - 2). This is the desired equation in point slope form.
To find the equation in standard form, perform the multiplication as follows:
y - 4 = 2x - 4. We want this to look like Ax + By = C.
Thus, subtract 2x from both sides:
-2x + y = -4, or
2x - y = 4 This is the desired equation in Standard Form.
