Answer:
Slope: 16
y-intercept: (0, 0)
Yes it is proportional
Step-by-step explanation:
What's the slope
To find the slope we can do rise over run.
192 - 96 96
----------------- = ----------- = 16
12 - 6 6
So the slope is 16
What is the y-intercept?
For the y intercept we can just look where the line crosses the y-line so (0, 0)
We can check that by inputing some numbers:
y = mx + b -------> 96 = 6 · 16 + b
96 = 96 + b
- 96 - 96
0 = b
in this equation b represents the y-intercept
Is it proportional?
And the definition of a proportional slope is if the equation is y = mx, which in this case it is true, as the equation is y = 16x. (m is the slope which we've already found above)
So evidently the slope is proportional.
