slope = 3
y-intercept= 2
slope = 1/3
y-intercept = -4

write an equation of the line?
2007-10-21 10:07:57 · update #1
If lines are parallel they will have the same slope. Your lines have slopes of 3 and 1/3 which are not equal (obviously) so the lines are not parallel.
The slope + y intercept form of the equation is y = mx + b where y = slope of the line and b = y intercept. Your equations become
y = 3x + 2 and
y = 1/3x - 4 or 3y = x - 12

Use the slope-intercept form of the equation of a line: y = mx + b. you have x, y and m, so plug those into the equation and sparkling up for b. you are able to now write the final equation for any element (x, y) utilising the values for m and b which you have.

use the formula y=mx+b
y = slope*x + y-intercept
so here are your problems
y=3x+2
y=1/3x+-4
