Step 1. Subtract 1 from bot sides of the equation:
A-1=1-1+prt
A-1=prt

Step 2. Divide both sides of the equation by pt:
\frac{A-1}{pt} = \frac{prt}{pt}
\frac{A-1}{pt}=r
r=\frac{A-1}{pt}

We can conclude that  after solving the equation A=1+prt; for r, we get r=\frac{A-1}{pt}

Write an equation in slope-intercept form for the line with slope 1/4 and y intercept -4. Then graph the line​
quester [9]

Answer:

Step-by-step explanation:

slope intercept form is y = mx + b

b is the y intercept ( crossing y axis value)....     by inspection   b = -4

m is the slope of the line,  Slope = m = 1/4      note: the slope is positive

the slope equals the 'rise' over 'run'  

if the line moves up the slope is positive, if the line moves down the slope is negative

the rise is how many y units does the line go 'up' or 'down'

the run is how many x units does the line go 'left' or 'right'

the rise = 1  Y unit

the run = 4 X units

y = mx + b    m =1/4  b = -4

y = (1/4)x + (-4)

y = (1/4)x - 4

graph a line stating at y = -4 and going up (rising) to the right ONE Y Unit for  every FOUR X units (the run)
