Question

Please help? I, unfortunately, am absolutely dreadful at Functions and Linear Equations. This was one of my questions. Please help.

Which of the following best describes the technique used to graph the equation, y = -2x + 8, using slope and y-intercept?

Answer 1

A)Mark a point at 8 on the y-axis, move upward 2 and right 1, mark the point and draw the line.
B)Mark a point at 8 on the y-axis, move downward 2 and right 1, mark the point and draw the line.
C)Mark a point at -2 on the y-axis, move upward 8 and right 1, mark the point and draw the line.
D)Mark a point at -2 on the y-axis, move downward 8

Answer 2

When x=0 then y=?

Answer 3

-10?

Answer 4

Ur given equation is
Y=-2x+8

Answer 5

Put x=0 in ur equation

Answer 6

Y=-2*0+8
