Using the slope and the y-intercept, graph the line represented by the following equation. complete your work in the space provided or upload a file that can display math symbols if your work requires it. include the graph of the linear equation, 2x - y + 4 = 0.

see the explanation

The graph in the attached figure

Step-by-step explanation:

we have

This is the equation of the line in standard form

Convert to slope intercept form

where

m is the slope

b is the y-intercept

Isolate the variable y

Adds y both sides

Rewrite

therefore

the slope m is

The y-intercept is the point (0,4)

To graph a line we need two points

using the slope

The slope of (+2) tells us that for every unit increment (i.e. +1) of the x

value, the y  value changes by ( +2)

we have the point (0,4)

so

For x=0+1=1 -----> y=4+2=6

therefore

we have the points (0,4) and (1,6)

Plotting these coordinates on the Cartesian plane and drawing a straight line

see the attached figure

rick has $1400 and sally has $1500

step-by-step explanation:

to find amount of money rick has after 10 years :

principal = $1000 , time = 10 years , rate = 4% annually

to find amount of money sally has after 10 years :

her friend gives to pay her $50 per year, therefore money she has after 10 years = 50 × 10 = $500

also, sally gets $1000 after 10 years,

therefore, total amount of money sally has after 10 years = 500 + 1000 = $1500

so, after 10 years : rick has $1400 and sally has $1500

to find the perimeter of the rectangle this is the expression:

x-9+x-9+3x-4+3x-4=138

if we simplify it:

8x-26=138

remember, 138 is what it all adds up to

the length is 11.5cm

the width is 57.5cm

the area is 661.25cm^2
