I need major help, again TvT

Answer:

Step-by-step explanation:

first graph the y-intercept. when x=0, y=-3, so graph a point at (0,-3). since this is a straight line, we only need to graph one more point to find the line. since the slope is -1/5, we can plug in 5 for x to find integer points. when x=5, y=-1/5*5 -3 = -1-3=-4. so another point on the line is (5,-4). then just connect the two points to find the line

Joan wrote a linear function.
12345 [234]

Answer:

A: true

B: true

C: false

D: true

E: true

Step-by-step explanation:

A: always true, m is the slope, and b is the y-intercept (starting value)

B: always true, m is always constant within the equation

C: false, initial value can be 0, e.g. in the equation y=5x, the initial value is 0

D: always true, being a line is part of the definition of linear

E: true, if the equation is in the form x = [a number], it is a vertical line where the x value is always the given number

How many ways can 4 people arrive at a party?
bonufazy [111]
We are going to name the people A, B, C, and D
1. A, B, C, then D
2. A, B, D, then C
3. A, C, B then D
4. A, C, D, then B
5. A, D, B, then C
6. A, D, C, then B
So at this rate, if there is 6 for the first letter, then there will be 6 for the others, so 6 x 4 = 24, so there are 24 different outcomes.
Hope this helped!
