Ndicate in standard form the equation of the line through the given points. P(0, -4), Q(5, 1)
tatuchka [14]

Answer:

y=x-4

Step-by-step explanation:

Standard form is y=mx+b

the coordinates (0, -4) tell you that the y intercept is at -4 which means b will be -4. To find slope you have to find the change in y over the change is x. 1--4=5 and 5-0=5. 5/5 is 1 so the slope, or m, is 1. x stays the same since it's the variable. it'll become y=1x-4 and since you don't have to place a coordinate of one in front of a variable, you can just write it as y=x-4

katovenus [111]

Answer:

The answer to your question is   0 < x ≤ 3

Step-by-step explanation:

To write this inequality we must consider

- The value of the borders, for this inequality the borders are 0 and 3.

-The kind of border   - if it is an open point, we will use the symbol  <

                                  - if it is a close c point, we will use the symbol ≤

-The inequality for this problem will be
