What is the slope-intercept form of the linear equation 4x + 2y = 24? Drag and drop the appropriate number, symbol, or variable
Morgarella [4.7K]

The slope-intercept form of the linear equation 4x + 2y = 24 is y =-2x+12

Step-by-step explanation:

We need to write slope-intercept form of the linear equation 4x + 2y = 24

The standard equation of slope-intercept form is:

y=mx+b

Converting given equation in slope-intercept form.

4x + 2y = 24

Add -4x on both sides

2y = -4x+24

Divide both sides by 2

y =-2x+12

So, the slope-intercept form of the linear equation 4x + 2y = 24 is y =-2x+12

Find the equation of the line that passes through the points (3,-2) and (6,-8)
Karolina [17]

Answer:

2x + y = 4

Step-by-step explanation:

The two-point form of the equation of a line is:

y - y_1 = \dfrac{y_2 - y_1}{x_2 - x_1}(x - x_1)

We have:

x1 = 3

y1 = -2

x2 = 6

y2 = -8

Plug in all the values where they belong in the equation above.

y - (-2) = \dfrac{-8 - (-2)}{6 - 3}(x - 3)

Simplify.

y + 2 = \dfrac{-6}{3}(x - 3)

y + 2 = -2(x - 3)

y + 2 = -2x + 6

2x + y = 4
