Answer:
Slope-Intercept: y = -x + 5
Point-Slope: y - 5 = -1x
Step-by-step explanation:
Slope intercept is known as y = mx + b, where m is the slope, and b is the y-intercept. To find slope, you can count or use the slope formula, and you should get -1. The y intercept is where x = 0, and in this case, b = 5.
Point slope can be altered to make slope intercept so this makes this part easier. The general formula is y - y1 = m(x - x1), where y1 and x1 are coordinate points and m is the slope. We already know slope from earlier, -1, so now we just need a coordinate point. You could use (0, 5). Now plug in the points; 0 for x1 and 5 for y1. Simplify and you're done.
Answer:
7.5 weeks
Step-by-step explanation:
Divide the amount by the rate to find the time:
(3/4 bag)/(1/10 bag/week) = 30/4 week = 7.5 weeks
