Question

Which of the following is not a step used when graphing the equation y = −x + 8 using the slope-intercept method?
Explain the correct order of steps needed to graph this equation, using the slope-intercept method.

Answer 1

Correct order of steps:
\[y=-x+8\]
since
\[y=mx+b\] is the slope-intercept form where m is the slope and b is the y-intercept:
m=-1, b=8.

plot (0,8) or 8 in the y-axis. next, use the slope to get another point needed to define the line. the point needed is (0+1,8-1)=(1,7), since -1=-1/1 (-1 is y, 1 is x).

then draw the resulting line from tracing a line through the two plotted points :))

Answer 2

your slope is -1, which is equal to delta y/delta x = -1/1
