Slope-intercept form: y = mx + b [m is the slope, b is the y-intercept or the y value when x = 0 ---> (0, y) or the point where the line crosses through the y-axis]
y = 25x + 125
"y" would represent the total amount of $ she has saved.
The y-intercept would be 125 or (0, 125), this means that she already/initially had $125 in her savings account, before she started depositing $25 per week
Let y=4x-1
The inverse is basically expressing x in terms of y.
y=4x-1 =>
y+1=4x
x=(y+1)/4
Since the inverse is still a function of x, we only have to interchange x and y
inverse of f(x) = f^-1(x) = (x+1)/4
Answer:
D
Step-by-step explanation:
Answer:
The linear equation that represents each function is y=mx+b. While The m represent the slop so instead of writing you write the slope provided. Then multiply by the X + b which is your Y-intercept.
Here is an example,
The slope is 2/3 and the y intercept is 6, write a linear equation for this sequence.
y= (2/3). X +6
