do you know how to find the slopes of the points ?

lets find the slopes using the slope formula : slope(m) = (y2 - y1)/(x2 - x1) set 1 (0,4) x1 = 0 and y1 = 4 (-2,8) x2 = -2 and y2 = 8 lets sub our info in : m = (8 - 4) / (-2 - 0) m = 4/-2 m = -2 <-- slope you see how I found the slope for set 1 ?
anonymous
  • anonymous
yes but it says The slope of Set #1 is smaller than the slope of Set #2. The slope of Set #1 is larger than the slope of Set #2. The slope of Set #1 is the same as the slope of Set #2. None of the statements above describes slopes of sets shown.

  • anonymous
now we need to find the slope of set 2 and compare them. m = (y2 - y1) / (x2 - x1) (3,7) x1 = 3 and y1 = 7 (-1,-5) x2 = -1 and y2 = -5 m = (-5 - 7) / (-1 - 3) m = -12/-4 m = 3 slope for set 1 is -2 and slope for set 2 is 3 so what do you think the answer is ?

Which of the following is not a step used when graphing the equation x + 3y = 3 using the x- and y- intercepts method? Plot the y-intercept (0, 1). Plot the intercept (3, 0). Count down 1 and right 3 from the y-intercept. Draw a line through the two points

i think its b

i mean c

it is C

i got What is the slope of the line 2x - 5y = -10? negative five halves five halves two fifths negative two fifths none of the above
anonymous
  • anonymous
nd i think its none of the above
anonymous
  • anonymous
2x - 5y = 10 -5y = -2x + 10 (multiply by -1 to make y positive) 5y = 2x - 10 (now divide by 5) y = 2/5x - 2 y = mx + b and m is your slope, therefore your slope is 2/5
anonymous
  • anonymous
wait...I wrote the problem down wrong...hold on
anonymous
  • anonymous
ok
anonymous
  • anonymous
2x - 5y = -10 -5y = -2x - 10 5y = 2x + 10 y = 2/5x + 2 it didn't matter, the slope is still 2/5

Explain how to graph 2x + y = 14 using the x- and y-intercepts method. Be sure to use complete sentences and use the x- and y-intercepts method only.
anonymous
  • anonymous
to find the x intercept, sub in 0 for y. 2x + y = 14 2x + 0 = 14 2x = 14 x = 7 <-- x intercept = (7,0) to find the y intercept, sub in 0 for x 2x + y = 14 2(0) + y = 14 y = 14 <-- y intercept = (14,0) so you have a point on the x axis at 7 and a point on the y axis at 14. Now just draw a line connecting the two points.
