Answer:

Step-by-step explanation:

$m=\frac{y_2-y_1}{x_2-x_1}\\ \\ m=\frac{3-1}{5-4}=2\\ \\ \text{y increases by 2 for every 1 increase in x.}$

A student studied for 1 hour and earned a 50% on her test. If she had studied for 2

marshall27 [118]

You have to double 1 and 50 to get 2 and 100

1:50 = 2:100

1x2=2

50x2=100

So the statement, <em>if she studied for 2 hours, she would have gotten 100%</em>, makes sense

Hope this helps!

Option A.

Step-by-step explanation:

While proving a number to be irrational, we usually start with the assumption that the number is rational . In the same way here , we will assume the opposite of the inequation to be proved , that is, x < 3 .

Write an inequality to represent the graph?

padilas [110]

Answer:

$\large\boxed{y>\dfrac{5}{2}x-3}$

Step-by-step explanation:

<, > - dotted line

≤, ≥ - solid line

<, ≤ - shaded region below the line

>, ≥ - shaded region above the line

We have dotted line (<, >) and shaded region above the line (>, ≥).

Therefore your answer is:

$y>\dfrac{2}{5}x-3$ or $y>\dfrac{5}{2}x-3$

Calculate the slope.

The formula of a slope:

$m=\dfrac{y_2-y_1}{x_2-x_1}$

Put the coordinates of the given points from the graph:

(0, -3) and (2, 2):

$m=\dfrac{2-(-3)}{2-0}=\dfrac{5}{2}$
