Help PLS BRAINLIST Rate of change on both of them pls look down below

Step-by-step explanation:

Rate of change is another term for the slope.

rate of change = slope = (change in y)/(change in x)

Function A:

y = mx + b (m = slope)

y = 4x - 3

Function A has a slope of 4.

The rate of change for function A is 4.

Function B:

Take two points.

(-1, 0) and (1, 4)

slope = (y2 - y1)/(x2 - x1)

slope = (4 -0)/(1 - -1)

slope = 4/2 = 2

The rate of change for function B is 2.

x=-2

infinite number of lines, so there is an infinite number of equations.

step-by-step explanation:

there are an infinite number of line that passes through the point (-2,5)

x=-2   is one line that passes through the point

y = 5 is another line that passes through the point

(these two lines are perpendicular to each other).

since the number of   numbers are infinite and the slope is the ratio of two numbers,(change in y over change in x) we can have an infinite number of slopes.     our only condition is that it passes through the point (-2,5)
