Which of the following best describes the technique used to graph the equation, y = -2x + 8, using slope and y-intercept? Mark a point at 8 on the y-axis, move upward 2 and right 1, mark the point and draw the line. Mark a point at 8 on the y-axis, move downward 2 and right 1, mark the point and draw the line. Mark a point at -2 on the y-axis, move downward 8 and right 1, mark the point and draw the line. Mark a point at -2 on the y-axis, move upward 8 and right 1, mark the point and draw the line.
Isn't this the same question? :O
Do you need me to explain it again?
yesss:)
y = -2x + 8 -2 is your slope. 8 is your intercept.
Can you tell what the answer is from that graph?
What 2 answers are you immediately going to cross out? Knowing that 8 is the y intercept?
c and d
@dtan5457
Good. Now, since this is a negative slope, do you move upwards or downwards?
upwards?
Upwards-positive slope
so its A. Mark a point at 8 on the y-axis, move upward 2 and right 1, mark the point and draw the line.
@dtan5457
It would be A if it was a positive slope or y=2x+8 However it is a negative slope, it goes DOWNWARDS.
so B @dtan5457 cuz it go down
yes
thank you
