The equation of the line in slope-int form is written as y=mx+b
Answer:
3. -2
4. 12
5. -4
Step-by-step explanation:
For all problems, let n represent "a number." You will note that when we specify an operation to be done on the equation, it is done to <em>both sides of the equation</em>.
__
3. 5n +(-3) = -13
5n = -10 . . . . . . add 3
n = -2 . . . . . . . . divide by 5
The number is -2.
__
4. (n/2) -7 = -1
n/2 = 6 . . . . . . . add 7
n = 12 . . . . . . . . multiply by 2
The number is 12.
__
5. 2n -1 = -9
2n = -8 . . . . . add 1
n = -4 . . . . . . divide by 2
The number is -4.
Slope = (y2-y1) / (x2-x1)
=( (-4) - 1) / ( 1 - 2)
= (-5) / (-1)
=5
