Answer:
Y
Step-by-step explanation:
Answer:
Monday: 4 hours = $36
Tuesday: 6 hours = $54
Wednesday: 5 hours = $45
His earnings are proportional because, for each hour, Richard earns $9. Using the formula y = kx, k (the constant) is always the same:
- 36 = k × 4 (k = $9)
- 54 = k × 6 (k = $9)
- 45 = k × 5 (k = $9)
Hope this helps!
The easiest way to do this is by graphing the equation. I'll do it:
We see that the y intercept is 11.
Formula for slope-intercept: y = mx + b
mx = slope
b = y-intercept
Now we have y = mx + 11. What's mx? We can find that out from the graph.
Let's find two points: (0,11) (4,3)
Using <span> (y2 - y1)/x2 - x1): We see that the slope is -2.
Now we finish the slope-intercept form and plug it all in:
y = -2x + 11
