So he went from 800 to 500. How many feet did he go up (be careful of the sign). And he did that in 5 minutes. How many feet per minute is that?2. A hang glider takes off from an 800-ft cliff. After 5 minutes he is at an altitude of 500 ft.
A. Determine the rate of change
Again, y= mx+ b (x is the time in minutes here). You got the slope, m, in (A) and when x= 0 y= 800.B. Write a linear equation to model the situation
"Slope intercept form" is "y= mx+ b". Solve for y.3. Rewrite -3x+6y=12 in slope intercept form
Again, y= mx+ b.4. Write an equation in point-slope form of the line passing through (-2,6) with slope -5/7
If m1 and m2 are the slopes of two perpendicular lines, then m1m2= -1.5, The line perpindiuclar to y=-3x-1 has a slope of....
Surely the problem did not say "the" line. There are an infinite number of lines parallel to this or any line. Two lines are parallel if and only if they have the same slope.6. Write an equation of the line parrallel to y=-1/2x+9
