Answer:
-24a-40y
Step-by-step explanation:
The equation of a line with slope m, and y-intercept b, is given the by the slope-intercept y=mx+b.
From the given detail, the slope is 7 and the y-intercept is 0. So, if we substitute m=7 and b=0, the equation becomes y=7x+0 or simple y=7x.
The required equation is y=7x.
Answer:
point(3.5 , 7.25)
Step-by-step explanation:
Given in the question,
pointA(2,8)
pointB(8,5)
To find,
A point which partition AB into 1:3
x1 = 2
x2 = 8
y1 = 8
y2 = 5
a = 1
b = 3
Formula to use
<h3>x' = x1 + (a/a+b)(x2-x1)</h3><h3>y' = y1 + (a/a+b)(y2-y1)</h3>
Plug in the values
x' = 2 + (1/1+3)(8-2)
= 3.5
y' = 8 + (1/1+3)(5-8)
= 7.25
So, point(3.5 , 7.25) partitions the directed line segment AB into a 1:3 ratio
