Question 171439: I have been working on these two problems for over a hour. PLEASE HELP! Question 1. find the slope-intercept equation of the line that has the given characteristics. Slope 8 and y-intercept (0.3) The slope-intercept equation is Y=? Number two question Find the slope-intercept equation of the line that has the given characteristics. Slope 2.8 and y-intercept (0.-3) The slpoe-intercept equation y=?
Answer by Mathtut(3670) (Show Source): You can put this solution on YOUR website!
ok the equation to use when you have a point and the slope is the point slope form. so we begin with that and they want the end result in slope intercept form
slop intercept form is y=mx+b where m is the slope and b is the y intercept
:
point slope form is y-k=m(x-h) where m is the slope and (h,k) is a point on the line
1.) y-3=8(x-0)---->y-3=8x---->
:
2.) if the slope really is 2.8 I will plug that in if its 28 just plug that in everywhere you see 2.8. by the way ordered pairs dont have a point to seperate the numbers it is a comma like our point in this problem would b(0,-3) not
(0.-3).
:
:
y-(-3)=2.8(x-0)--->y+3=2.8x---->
