i really need to know the equation of the line that is shown on the graph in slope intercept form (y=mx+b). questions 4-9. it’s

melamori03 [73]

Step-by-step explanation:

4. y=-6/3x+3 (if you can simplify put y=-2x+3)

5. y=5/2x+1

6. y=-8/2x -5 (if you can simplify put y=-4x-5)

7. y=-6/6x+2 (if you can simplify put y=-x+2)

8. y=4/6x-4 (if you can simplify put y=2/3x-4)

9. y=6/5x+0

hope this helped!!!

What is the value of x? Enter your answer, as a decimal, in numerical value only.

Doss [256]

Answer:

x = 67.5

Step-by-step explanation:

If a line is parallel to a side of a triangle and intersects the other 2 sides , it divides those sides proportionally.

AB is parallel to NP and intersects the other 2 sides , then

$\frac{MA}{AN}$ = $\frac{MB}{BP}$ ( substitute values )

$\frac{71.5-22}{22}$ = $\frac{x}{97.5-x}$ , that is

$\frac{49.5}{22}$ = $\frac{x}{97.5-x}$ ( cross- multiply )

49.5(97.5 - x) = 22x ← distribute left side

4826.25 - 49.5x = 22x ( add 49.5x to both sides )

4826.25 = 71.5x ( divide both sides by 71.5 )

67.5 = x

Slope of points (2,3) and (-4,12)

Ira Lisetskai [31]

Answer:

$\huge\boxed{slope=-\dfrac{3}{2}}$

Step-by-step explanation:

The formula of a slope:

$m=\dfrac{y_2-y_1}{x_2-x_1}$

We have the points (2, 3) and (-4, 12).

Substitute:

$m=\dfrac{12-3}{-4-2}=\dfrac{9}{-6}=-\dfrac{9:3}{6:3}=-\dfrac{3}{2}$
