we have the equation
y=-(1/2)x+7
Remember that
To graph a line we need al lest two points
so
Find the intercepts
step 1
Find the y-intercept (value of y when the value of x is zero)
For x=0
y=-(1/2)(0)+7
y=7
y-intercept is (0,7)
step 2
Find the x-intercept (value of x when the value of y is zero)
For y=0
o=-(1/2)x+7
(1/2)x=7
x=14
x-intercept is (14,0)
step 3
Plot the intercepts and join them to graph the line
using a graphing tool
see the attached figure
please wait a secon to draw the line
