Answer:
y=-2x +8
Step-by-step explanation:
You need to expand (4x-7)(x+3), multiplying each term in the first bracket by each term in the second bracket, in order to get 4x^2+5x-21. Hope that helps!
It could be a linear graph with a negative slope
x axis is height above ground and y axis id air pressure
so there willbe a point at (0,14.7) on y axis representing the pressure at sea level. There will be another point at (3.6, 7.35) where air pressure is half that at ground level. The straight line will continue until it reaches the x axis ad (0, 7.2) where there is no air pressure.
