Question

PRETTY PLEASE HELP Me! ;)

What is the equation of the line in slope-intercept form?
Write your answer using integers, proper fractions, and improper fractions in simplest form.

Answer 1

hi!
Answer:
y = -x

Step-by-step explanation:
For every time y increases by 1, x decreases (goes down) by 1. You can see that the slope is negative as it seems to go ‘down’ rather than go ‘up’.
You could say the equation is y= -1x, but because there is only one ‘x’ we can just leave it as -x.
Hope this helps :)

Answer 2

y = -1x

gradient = -1

rise/run= +10-20/-10+20

= -10/10

= -1

y intercept is 0 as line is passing through 0 on y axis

For verification:

input any pair of x and y values in y = mx + b

10=-1(-10)+b

10=10+b

b= 10-10

b=0

Equation:

y = -1x
