-y=8-2x

multiply each side by -1 (to get rid of NEGATIVE y)

y=2x-8

where: rise: 2; run: 1 is the slope

and -8 is the y-inercept

and then:

y=-x+1

where: rise: -1; run: 1 is the slope

and 1 is the y-intercept

follow these rules and sketch.

When you set it up like that you should get y=2x-8 and y=-1x+1.

Have each respective line cross through the y-intercept and have the correct slope and hit the point of interception.

Hope this rings a bell and helps.

solve each equation for y, then choose values for x and calculate the new value of y

the first equation is y = 2x – 8

the second equation is y = -x + 1

make tables of values and plot the points to form the line

first you have to draw two lines seperately and then check for intersection point
