I'm pretty sure that a rate is a ratio and a ratio is a rate because 2:3 can be saying a rate and it can be a ratio as well. I don't know how to explain it very well so sorry
Answer:
y= -4/3 + 22
Step-by-step explanation:
y= -4/3x -1
14 = -4/3 (6) + b
14= -8 + b
22= b
Answer:
Step-by-step explanation:
1) Mark two points on the line in the graph.
2) Determine the rise and run. Rise ---> difference in y-coordinates. (y2-y1)
Run -----> difference in x-coordinates (x2 - x1)
3) Plugin the values in the below mentioned formula.
1.If slope = 0, then the line is parallel to x-axis.
2. If slope is undefined, then the line is parallel to y-axis.
3. If slope is +ve, then the line slant upwards and if slope = -ve, then the line slant downwards.
Answer:
1a: f(-2) means substituting -2 for x
1b: 65
I don't know the second one
