To graph the line, we must first find out the equation for the line in slope-intercept form (y = mx + b). So far, we only have the slope, so the line's equation is y = 3/4x + b. But, by inserting the values of x and y in the point we know, we can find the y - intercept.
4 = 3/4 + b
b = 13/4
That means that the equation of our line is y = 3/4x + 13/4. Now we can graph. But, there is another way to go about (slightly faster too). Since we know the coordinates of 1 point, we can put that line down. Then, since we know that slope is rise over run, we can say, that with a slope of 3/4, one would go 3 points up for every 4 to the right. Now we can go 3 points up and 4 points to the right of point (1,4). That would be (5, 7). Now we can graph (since we have 2 points, or an equation).
The graph looks like this:
Answer:
√23 is the answer of the question
Answer:
2
Step-by-step explanation:
From the graph, we obtain the trigonometric function as:

The corresponding cosine function have equation.

This function is of the form: 
where
is the amplitude.
Therefore the amplitude is |2|=2
The third choice is correct
4/6 = 1/x cross multiple so x= 1.5 dollars
