Question

Please help me

y=-2x+2
y=2x+2
y= -1/2x+2
y= 1/2x+2

Answer 1

y = mx + b

"m" is the slope, "b" is the y-intercept [the y value when x = 0, so (0,#)]

You can find the slope by using the slope formula and plugging in 2 points:

`m =(y_(2)-y_(1))/(x_(2)-x_(1))`

Or you can use this:

`slope=(rise)/(run)`

Rise is the number of units you go up(+) or down(-)

Run is the number of units you go to the right.

If you look at the graph, from each point you go down 2 units, and to the right 1 unit, So you slope is -2/1 or -2. When x = 0, the y value is 2, so your y-intercept is 2.

y = -2x + 2 The first choice is your answer

Answer 2

Okay well, just by looking at the graph. It’s a negative slope and the only answer, that has a negative is the 3 one.
