Question

What is the equation of this line? y=12x−2 y=2x−2 y=−12x−2 y=−2x−2 Number graph ranging from negative ten to ten on both the x and y axis. A line passes through the point begin ordered pair 0 comma negative 2 end ordered pair and the point begin ordered pair 4 comma 0 end ordered pair

Answer 1

y=1/2 x-2

Explanation:

Answer 2

Explanation:

slope-point form:

y=mx b

We need two points to work out the slope; for example in this line we have:

(0,-2)

(4,0)

m=(y₂-y₁)/(x₂-x₁)

m=(0+2)/(4-0)=2/4=1/2

In this line the y-intercept (b)=-2

The equation of the line will be: y=1/2 x-2

Answer: y=1/2 x-2
