For the equation y = 7x – 2, what is the rate of change? what does it mean? explain your answer in simple terms !

slope is 7

Step-by-step explanation:

the rate of change is the slope

in the general equation y = mx + b

x and y are point coordinates (x,y)

b is the y intercept

m is the slope

this is the rate at which the points are changing essentially

a larger slope will produce a steeper line

a negative slope will produce a line pointed downward

a smaller slope will produce a flatter line

step-by-step explanation:

∠acb = 8°

step-by-step explanation:

∠xba lies on the circle and is half the measure of the intercepted arc ax

hence

measure of arc ax = 2 × 42° = 84°

∠acb is outside the circle and is

∠acb = (arcab - arcax ), hence

∠acb = 0.5 (100 - 84) = 0.5 × 16° = 8°
