If a linear equation is written in the form y = 1/2x - 2 , which method could be used to graph the line represented by the equation?

Plot the x-intercept (-2,0) and use the slope of 1/2 to find a second point.

Plot the y-intercept (0,1/2) and use the slope of –2 to find a second point.

Plot the x-intercept (1/2,0) and use the slope of –2 to find a second point.

Plot the y-intercept (0,-2) and use the slope of 1/2 to find a second point.

Do you know what the m and b are in y = mx + b ?

anonymous · Answer

m is slope.
b is the y intercept.

anonymous · Answer

Right. So you know those things. We don't know the x-intercept so we can't use that.

anonymous · Answer

Wouldn't it be d because the y intercept is -2

anonymous · Answer

Yes
