Answer:

The gradient of the graph below is $\mathbf{\frac{3}{2} }$

Step-by-step explanation:

We need to calculate the gradient of the graph

The gradient of graph is actually slope of the graph.

The slope of graph can be calculated using formula: $Slope=\frac{y_2-y_1}{x_2-x_1}$

Taking any 2 points on graph i.e

(1,0) and (-1,-3)

We have $x_1=1, y_1=0, x_2=-1,y_2=-3$

Putting values and finding gradient:

$Slope=\frac{y_2-y_1}{x_2-x_1}\\Slope=\frac{-3-0}{-1-1}\\Slope=\frac{-3}{-2}\\Slope=\frac{3}{2}$

So, The gradient of the graph below is $\mathbf{\frac{3}{2} }$

The price for 11 ballpoint pens is $11.77. Which of the following represents the same price per pen? A. 4 pens for $4.44 B. 5 pe

Harrizon [31]

First we need to know how much each pen costs. So we take 11.77 and divide it by 11. That gives us 1.07 per pen. So answer choice A has 4 pens for 4.44, so we need to multiply 1.07 x 4. That gives you 4.28, so we know that isn't the correct answer. For option B, we need to multiply 1.07 x 5. That is 5.35, so that also can't be the answer. For C, we need to do 1.07 x 6, and that gives us 6.42. So we know the correct answer is option C.
