Which equations have the same slope as the graph above? Select all that apply.
borishaifa [10]

Given:

The graph given passes through two points (0, 2) and (-4, 8).

General Idea:

We can find the slope (m) of a line passing through two points say A and B using the below formula.

A(x_1,y_1) \; and \; B(x_2,y_2) \; the\; two\; points\\ \\ Slope\; (m)\; =\;   \frac{y_2-y_1}{x_2-x_1}

Applying the concept:

Slope of the line given using the two points (0, 2) and (-4, 8).

m=\frac{8-2}{-4-0}=\frac{6}{-4}  =\frac{-3}{2}

Out of the five options given , we need to check which options have slope as -6/4 or -3/2 by rewriting (if needed) the given to slope intercept form y =mx + b and compare the same.

Conclusion:

Rewriting the first option, the slope is -6/4 as shown below.

y=\frac{12-6x}{4}=\frac{12}{4} -\frac{6x}{4}  =-\frac{6}{4}x+3

Rewriting the fourth option, the slope is -3/2 as show below.

-4y=6x+4\\ \\ \frac{-4y}{-4}=\frac{6x}{-4}+\frac{4}{-4}   \\ \\ y=\frac{-3}{2}x-1

Rewriting the fifth option, the slope is -3/2 as shown below.

2y+3x-5=0\\Subtract \; 3x\; and\; add\; 5\; on\; both\; sides\; of\; the\; equation\\ \\ 2y+3x-5-3x+5=0-3x+5\\ Combine\; like\; terms\\\\ 2y=-3x+5\\

Divide by 2 throughout the equation

\frac{2y}{2} =\frac{-3x}{2}+\frac{5}{2}  \\ \\ y=\frac{-3}{2} x+\frac{5}{2}

If ABCD is an isosceles trapezoid, what is the value of x
Grace [21]

Answer:

Since we know that ABCD is an isosceles trapezoid, we can also asume that its diagonals have the same length, which means:

AC = BD

=> 7x - 21 = 5x + 13

=> 7x - 5x = 21 + 13

=> 2x        = 34

=> x           = 34/2 = 17

So the answer is C.
