Answer:
y = x-20
Step-by-step explanation:
<h2><u>finding the equation of the line</u></h2>
get 2 points A and B , they are an on the line
make sure its in the form (x,y)
A = (0 , -20)
B = ( 70 , 50)
<h2><u>now get the gradient</u></h2>
gradient =
=
= 70/70
gradient = 1
<h2><u>now make the equation</u></h2>
m is the gradient
y- y1 = m (x-x1)
y- -20 = 1 (x - 0)
y + 20 = x
put in the form y = mx +c
therefore
<u>y = x - 20</u>
