Graph the line with y-intercept 3 and slope -2?

Answer 1

The line with y-intercept 3 and slope -2:

y = -2 x + 3

Answer 2

put one point at the y-intercept

(0, 3)

Slope is rise/run

For a slope of -2 

drop y down 2;   from 3 to 1

move x right 1;   From 0 to 1

this is point (1, 1)

Draw a line through the two points

 

Answer 3

y = mx + b; where m is the slope and b is 

the y-intercept.

y = -2x + 3

Now solve once with x = 0 and again with y = 0.

You’ll end up with two pairs of points to draw your graph.
