Answer:
The point (2, -1 ) is not on the graph of the line.
Step-by-step explanation:
3x–4y–12=0
3*2 - 4*(-1) - 12= 0
6 + 4 - 12 =0
10 - 12 = 0
- 2 = 0 , false, so the point (2, -1 ) is not on the graph of the line.

Answer:
y=3x+4
Step-by-step explanation:
The equation of the straight line that passes through (-3,-5) with slope 3 can be found using

where m=3 is the slope .
We substitute the slope to get:

We substitute the point to find b.

The equation of the straight line is:
