Find the equation of the line. using exact numbers

let's take a peek at the line, to get the equation of a line all we need is two points on it, hmmm let's see say this line passes through (0, -2) and (4, 1), so let's use those

Step-by-step explanation:

The slope-intercept form of an equation of a line:

m - slope

b - y-intercept → (0, b)

The formula of a slope:

From the graph (look at the picture) we have two points

(-4, -5)

(0, -2) → b = -2

Calculate the slope:

Put it and the value of an y-intercept to the equation of a line:

answer: -8.2562234e+13

a) y = -3x +2

b) y = 1/2x -6

these 2 can be combined into one equation.

-3x +2 = .5x -6

8 = 3.5x

x = 8 / 3.5 = 2.2857142857

y = -3 * (8 / 3.5) +2

y = (-24 / 3.5) + 2

y = -4.8571428571
