Question

how do you find the intercept of the equation 19x + y = 0

Answer 1

you rewrite the equation in slope-intercept form, y=mx+b. in this case, it is y = -19x. you can now input y=o to get the x-intercepts and x=0 to get the y-intercepts.

Answer 2

okay thanks, oh and how would you find the slope of this equation?

Answer 3

m is the slope since we're using slope-intercept form

Answer 4

so in this case the slope would be -19?

Answer 5

you are correct, the slope is -19

Answer 6

ok cool..thanks

Answer 7

okay how would you determine the angle of intersection for the lines:
4x-y+2=0 and 19x+y=0

Answer 8

i know you would have to find the slope of both equations which i did but i'm getting \[\theta=17 when \it should be \theta=163\]

Answer 9

notice how 17+163 = 180, so you're just calculating the supplement to the actual angle that you want

Answer 10

ohhh thats what i didn't do..thanks once again

Answer 11

you're welcome
