The correct answer is letter B, (6,-1).
When you substitute this ordered pair on the equations, you would found out is the correct one.
Answer:m=250
Step-by-step explanation:
0.1m+8-3=30
0.1m+5=30
0.1m=25
0.1 times 250=25
m=250
Answer:

Step-by-step explanation:

It is y+1=0.9(x+4) because the formula is y - y1=m(x + x1) you only need one point and the slope. If you have two points, you need to find the slope by using the slope formula slope=y2-y1/x2-x1. Filling it in it would look like slope=7-(-1)/5-(-4). The double negatives cancel each other out and it turns to addition signs leaving us with slope=7+1/5+4 so the slope is 8/9 or 0.9. Now you can fill out the point-slope formula y+1=0.9(x+4)
