Y=mx+b
y=80x+25
for every hour you must pay 80$
how many hours is X
and B is the rate you must pay anyway for the lesson and how many hours you have rented.
Math I hate math bc it sucks
Answer:
7 rows
Step-by-step explanation:
total 42 tiles. 6 columns mean, each column will have 6 tiles. so to have 42 tiles, 6*7 required
If the equation is -(2/3) x - (1/4) y = 1/3, it is a straight line, so you can use some special points to identify the graph.
It is easier is you solve the equation for y:
(1/4)y = - 1/3 - (2/3) x
y = (-4/3) - (8/3)x
That is the slope -y-intercept form of the equation.
That means that the slope is -8/3, and the y-intercept is -4/3.
Use this points to identify the graph:
x = 0 => y = - 4/3 ---> (0, - 4/3)
y = 0 => x = - 1/2 -----> (-1/2, 0)
Now you can punt those two points on the graph and draw the line that joins them.
With this procedure you can find the graph of any straight line.
24 is the answer.........
