we can determine the value of this number by setting an equation
the sum of the number and 7, multiplied by 3, is equal to 8 plus the number.
making x= the unknown number, we can say:
3(x+7) = 8 + x
now we can distribute the 3 and solve for x
3x+21 = 8+x
2x+21=8
2x= -13
x = -6.5

Answer:
16. y=-5x-20; 17. y=6x+18, or factored y=6(x+3)
Step-by-step explanation:
Your slope is -5
y=-5x+b, solve for b by pluging the point (-3,-5) in for x and y
-5=-5(-3)+b, solve for b
-20=b, now rewrite the equation
y=-5x-20
Your slope is 6
y=-5x+b, solve for b by pluging the point (-3,-0) in for x and y
0=6(-3)+b, solve for b
18=b, now rewrite the equation
y=6x+18, or factored y=6(x+3)
