What is the slope, m, and y-intercept for the line that is plotted on the grid below?

slope = 2 and y- intercept = 4

Step-by-step explanation:

Calculate the slope m using the slope formula

m = (y₂ - y₁ ) / (x₂ - x₁ )

with (x₁, y₁ ) = (- 2,0) and (x₂, y₂ ) = (0, 4) ← 2 points on the line

m = = = 2

The y- intercept is the value of the y- coordinate where the line crosses the y- axis, that is

y- intercept = 4 or (0, 4) in coordinate form, thus

y = 2x + 4 ← equation in slope- intercept form

Step-by-step explanation:

The slope is defined as

Where we need two points on the line to use the slope formula.

The points we selected are and . Replacing this points, we have

Now, we use one point, the slope and the point-slope formula to find the equation

Where  and which is the y-intercept.

Therefore, the slope of the line is 2 and the y-intercept is at (0,4).

correct choice is b

step-by-step explanation:

when you calculate the average rate of change of a function, you are finding the slope of the secant line between the two points. for the function the average rate of change from point to point can be calculated as

to find the average rate of change from day 2 to day 10, note that at day 2, 8 houses were sold, so a(2,8) and at day 10, 2 houses were sold, so b(10,2). thus,

step-by-step explanation:

yes it represnts a functio, their are not 2 of the same numbers on the both sides
