7k/3 = 21
x 3 x3
7k = 63
/7 /7
k = 9
(7(9)/3 = 21 = 63/3 = 21 = 21 = 21)

Answer:
k = 3
Step-by-step explanation:
Given
4.5 + 1.5k = 18 - 3k ( add 3k to both sides )
4.5 + 4.5k = 18 ( subtract 4.5 from both sides )
4.5k = 13.5 ( divide both sides by 4.5 )
k = 3
Answer:
y=50x+75
Step-by-step explanation:
In a linear equation, the parent form of the line is called y=mx+b where m is the slope of the graph and b is the y-intercept.
Slope: We can start from any point on the graph and we can see that with one x value, the y increases every 50. 50 would be the slope in this case. It is the change of y over the change of x (50/1)
Y-intercept: The graph starts off on the left hand at the number 75, which means the number to plug in is 75.
