Answer:

-1.3

Step-by-step explanation:

The graph shows the straight line passing through the points (3,-1) and (-3,7).

The slope of the line passing through the points (x_1,y_1) and (x_2,y_2) is

\dfrac{y_2-y_1}{x_2-x_1}

In your case, the slope is

\dfrac{7-(-1)}{-3-3}\\ \\=\dfrac{7+1}{-6}\\ \\=-\dfrac{8}{6}\\ \\=-\dfrac{4}{3}\\ \\\approx -1.3

The rate of change is -1.3

When John bought his new computer, he purchased an online computer help service. The help service has a yearly fee of $25.50 and
Westkost [7]
The yearly fee can be subtracted, resulting in 170-25.50=144.5

So with 10.50 a session, you must divide, resulting in around 13.8 sessions.

13 sessions if you need a whole number.

Hope this helps

Step-by-step explanation:

If it is a right triangle then by the Inverse of the Pythagoras Theorem:

40^2 = 35^2 + 15^2

Testing:

40^2 = 1600

35^2 + 15^2 = 1225 + 225 = 1450

So the answer is NO>

Explain how to graph the equation y = 2x − 3 without using a table of values.
marin [14]
Y = mx + c 
m is the gradient of the graph, for each time you go across 1 x you go up y 'm' times, in your case you go up twice each time you go across once along x
c is the y intercept, the number where the y axis is cut and where you should start drawing your graph
