Question

What is the equation of this graphed line? (0,7) (8,-2)

Enter your answer in the slope-intercept form in the box.

Answer 1

Explanation:

eq. of line is y-7=(-2-7)/(8-0) (x-0)

y=-9/8 x+7

Answer 2

equation is y=1.3x-12.4

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
