Answer:

Y=2x+0.5

Explanation:

The gradient is 2/1=2x

The y-intercept looks to be around 0.5

Answer:

y =
(1)/(2) x +
(1)/(2)

Explanation:

The equation of a line in slope- intercept form is

y = mx + c ( m is the slope and c the y- intercept )

Calculate m using the slope formula

m =
(y_(2)-y_(1) )/(x_(2)-x_(1) )

with (x₁, y₁ ) = (- 1, 0) and (x₂, y₂ ) = (1, 1) ← 2 points on the line

m =
(1-0)/(1-(-1)) =
(1)/(1+1) =
(1)/(2) , then

y =
(1)/(2) x + c ← is the partial equation

To find c substitute either of the 2 points into the partial equation

Using (1, 1 ) , then

1 =
(1)/(2) + c ⇒ c = 1 -
(1)/(2) =
(1)/(2)

y =
(1)/(2) x +
(1)/(2) ← equation of line
