Graphing a line given its slope and y-intercept.

Question

Graph the line with slope -7 and y - intercept 6.

Answer 1

 slope -7 and y - intercept 6.

 

Slope intercept form: y = mx + b, m=slope, b = y-intercept

 

y = -7x + 6

 

Just plug in a value for x and solve for y

 

x     y=-7x+6

------------------

0           6

1          -1

 

If you plot these two points and draw a straight line through them,

that is the graph of the line.
