Answer: I believe the answer is (A) (-4,4) because the only corner that's going up towards the (f) is stopped over the 4's.

Write an equation in slope-intercept form that contains the points (2, 8) and (4, 9).

ololo11 [35]

Given two points, the equation of the line in slope form can be obtained using this equation

$\frac{y_2-y_1}{x_2-x_1}\text{ = }\frac{y_{}-y_1}{x_{}-x_1}$

Now we can name the points

x1 = 2, y1 = 8

x2 = 4 , y2 =9

These coordinates can then be substituted into the equation

$\frac{9-8}{4-2}\text{ =}\frac{y\text{ - 8}}{x\text{ - 2}}$

$\begin{gathered} \frac{1}{2}\text{ = }\frac{y\text{ - 8}}{x\text{ - 2}} \\ \\ x-2\text{ = 2 (y - 8)} \\ \\ x\text{ - 2 = 2y - 16} \end{gathered}$

x - 2 + 16 = 2y

2y = x - 2 +16

2y = x + 14

Divide both sides by 2

y = x/2 + 14/2

$y\text{ = }\frac{x}{2}\text{ + 7}$

This is the equation in slope-intercept form

where the slope = 1/2

M is the midpoint of YZ. If YM = x + 3, and YZ = 3x -1, find MZ

Elenna [48]

2(x+3)= 3x-1
2x+6=3x-1
X=7
Therefore
YM = 7+3= 10
And by definition of midpoint YM=MZ so MZ=10
