Answer:
y = -3x - 2
Step-by-step explanation:
Equation of a line passing through 
and slope m is,
Slope of a line passing through and 
is,
Slope = 
Slope of the line passing through (0, -2) and (1, -5) will be,
Slope = 
m = - 3
Therefore, equation of the line passing through (0, -2) and slope = -3 will be,
y + 2 = -3(x - 0)
y + 2 = -3x
y = -3x - 2
Answer:
The three consecutive integers are 19, 20, and 21. And 19 + 21 = 40.
Step-by-step explanation:
Let the first integer be x.
The next consecutive integer would be x + 1 and the next x + 2.
The equation for the sum of the first and third integer equaling 40 can then be written as:
x + (x + 2) = 40
Solving gives:
2x + 2 = 40
2x + 2 - 2 = 40 - 2
2x = 38
x = 19
Answer:
9.267
Step-by-step explanation:
The greatest factor of 60 and 75 is 15.
Reasoning: I found the factors and prime factorization of 60 and 75. The biggest common factor number is the GCF number. So the greatest common factor 60 and 75 is 15.
