What is the equation of this graphed line? (0,7) (8,-2)
2 answers:
Answer:
equation is y=1.3x-12.4
Step-by-step explanation:
Step one
Given that the points are
(0,7) (8,-2)
X1=0
X2=8
Y1=7
Y2=-2
Step two :
Let us find the Slope
Pluging our points we have
M= (Y2-Y1)/(X2-X1)
M=(-2-7)/(8-1)
M=-9/7
M=1.3
Step three :
We know that the equation of a line is given by
Y=Mx+c
Hence the intercept is
-2=1.3*8+c
-2=10.4+c
-12.4=c
c=-12. 4
Hence the equation is y=1.3x-12.4
Answer:
Step-by-step explanation:
eq. of line is y-7=(-2-7)/(8-0) (x-0)
y=-9/8 x+7

The formula is
YC x YD = AY x YB
fill in what we know:
18 x 6 = 9 x YB
108 = 9 x YB
YB = 108 / 9
YB = 12
A value that "lies outside" (is much smaller or larger than)
Answer:
slope= 10/9
y intercept= -11/9
Step-by-step explanation:
9y= 10x -11
y= 10/9x -11/9
slope= 10/9
y intercept= -11/9
