Answer:
$1000 ; 500 ; 1000 ; y = 500x + 1000
Step-by-step explanation:
From the graph, the initial deposit which started the savings account is $1000 ; this is the value on the y - intercept, the value in the account at time or period = 0.
The slope :
x1 = 0 ; y1 = 1000
x2 = 6 ; y2 = 4000
Slope = Rise / Run
Rise = y2 - y1 = 4000 - 1000 = 3000
Run = x2 - x1 = 6 - 0 = 6
Hence,
Slope = 3000 / 6
Slope = 500
y - intercept = 1000 (from. Graph)
Equation in slope intercept form:
General form : y = mx + c
m = slope ; c = intercept
Equation is written as ;
y = 500x + 1000
Answer: $8.95 per yard of fabric
Step-by-step explanation:
Define the following:
x = cost of fabric per yard
Make an equation:
⇒ 3x + 1.25 = 28.10
⇒ 3x = 26.85
⇒ x = 8.95
∴ $8.95 per yard of fabric
Answer:
y= -5
Step-by-step explanation:
x=0 is a vertical graph hence the perpendicular graph would be a horizontal line, a y= ____ graph.
Since it passes through the point (-2, -5),
the equation of the line is y= -5.
This would be in slope- intercept form since the gradient of horizontal lines is zero.
y= mx +c, where m is the gradient and c is the y-intercept.
Given that gradient =0, m=0
y= 0x +c
when x= -2, y= -5,
-5= 0(-2) +c
-5= c
c= -5
Thus the equation is y= -5.
