Question

I need some help please this is confusing to me ☹️

Answer 1

Answer:

well if you look at the y it equals y= x-20

Step-by-step explanation:

Answer 2

Answer:

y = x-20

Step-by-step explanation:

finding the equation of the line

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)

now get the gradient

gradient = $\frac{y2-y1}{x2-x1}$

= $\frac{50 - - 20}{70-0}$

= 70/70

gradient = 1

now make the equation

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

y = x - 20
