<span>The function h(t) = 210 – 15t has the slope-intercept form of the equation of a straight line. The y-intercept represents the amount h at the very beginning (when t=0). The negative slope (-15) represents the amount by which h will decrease if t is increased by 1.
We are manipulating the value of time, t, so time, t, is the independent variable, and h(t) = y is the dependent variable.</span>
Answer:
Step-by-step explanation:
Hi there!
<u>What we need to know:</u>
- Linear equations are typically organized in slope-intercept form: where m is the slope and b is the y-intercept (the value of y when x is 0)
- Parallel lines always have the same slopes
<u>1) Determine the slope (m)</u>
The given line has a slope of -2. Because parallel lines always have equal slopes, we know that the line parallel to this would also have a slope of -2. Plug this into :
<u>2) Determine the y-intercept (b)</u>
Plug in the given point (2,4) to solve for b
Add 4 to both sides to isolate b
Therefore, the y-intercept of the line is 8. Plug this back into :
I hope this helps!
