Plug in the coordinate (7, 10) into the equation so
10 = 1/2 (7) + b
You use b and not - 9 because you’re making a complete different equation so solve for b
10 = 1/2 (7) + b
Multiply 1/2
10 = 3.5 +b
Subtract 3.5 on both sides
6.5 = b
Plug b (6.5) back into the equation but flip the slope as a negative reciprocal because it’s asking for a perpendicular line so
y = -2 + 6.5 (your equation)

Someone explain to me how to get the correct answer
Bingel [31]
Graph : 
slope (rate of change) = (-2 - (-4) / (-2 - (-6) = 2/4 = 1/2
y int = (0,-1)
x int = (2,0)

f(x) = 2x - 2
slope(rate of change) = 2
y int = (0,-2)
x int = (1,0)

greater rate of change : f(x) = 2x - 2.....greater by 1.5
greater y int : graph....greater by 1
greater x int : graph...greater by 1
steeper graph : f(x) = 2x - 2

A toy airplane climbs 30 vertical feet while traveling 50 feet horizontally. A toy helicopter climbs 20 feet while traveling 40
PilotLPTM [1.2K]

Answer:

Slope is the change in y over the change in x. The toy airplane would then have a slope of 3/5 and the toy helicopter would have a slope of 1/2. As 3/5 is greater than 1/2, the toy airplane would have a greater slope.

Hope this helps!
