For the second question choose two points and subtract your y values and x values within your ordered pair

2. (10,50)(25,20)
slope = (20 - 50) / (25 - 10) = - 30 / 15 = -2

3. y = mx + b
slope(m) = -2
(25,20)...x = 25 and y = 20
now we sub and find b, the y int
20 = -2(25) + b
20 = -50 + b
20 + 50 = b
70 = b
ur equation is : y = -2x + 70

4. it would be a negative association because there is a negative slope. A negative association is when one variable increases, the other one decreases.

5. ?? there both negative

using the given quadratic function f(x)=x^2+2x-15, find the following information"Coordinates of y- intercept as an ordered pair

kifflom [539]

The y-intercept is the point at which a function cuts the y-axis. It can be found by evaluating the function at x=0. The coordinates of that point will be:

$(0,f(0))$

Evaluate f(0):

$\begin{gathered} f(x)=x^2+2x-15 \\ \Rightarrow f(0)=(0)^2+2(0)-15 \\ =0+0-15 \\ =-15 \end{gathered}$

Since f(0) = -15 , then the coordinates of the y-intercept are:

$(0,-15)$

Answer:

x = 20°

Step-by-step explanation:

given : x + 70° = 90°

( it is shown in the figure )

=》x + 70° = 90°
=》x = 90°- 70°
=》x = 20°

hence, x = 20°
