Write the equation of the line in fully simplified slope-intercept form.
fiasKO [112]

y = -\frac{1}{2}x - 1

Step-by-step explanation:

Let's pick two points on the line: P_1(-4, 1) and P_2(2, -2). Let's calculate the slope of this line using these points:

m = \dfrac{y_2 - y_1}{x_2 - x_1} = \dfrac{-2 - 1}{2 - (-4)} = -\dfrac{1}{2}

With this value of the slope, we can write the general slope-intercept form of the equation as

y = -\frac{1}{2}x + b

To solve for the y-intercept b, let's use either P1 or P2. I'm going to use P2:

-2 = -\frac{1}{2}(2) + b \Rightarrow b = -1

Therefore, the slope-intercept form of the equation is

y = -\frac{1}{2}x - 1

Answer:

Step-by-step explanation:

\frac{XY}{PQ}=\frac{YZ}{QR}\\\\\frac{19.5}{6.5}=\frac{10.5}{k}\\\\

Cross multiply,

19.5*k = 10.5 * 6.5

k =\frac{10.5*6.5}{19.5}\\\\k=3.5

For the law of cosines How am I supposed to know if I’m using SAS or SSS
seropon [69]

Answer:

SSS congruency is when you know that the two triangle you want to compare's sides have the same length. Since they have the same length, they are congruent. SAS congruency stands for "side, angle, side" and means that we have two triangles where we know two sides and the included angle are equal.
