What is the slope and y-intercept of line q graphed below?

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

1/3 and (0,1)

Step-by-step explanation:

In a cartesian plane, we can represent a line using a general equation defined in that plane. Given a line with slope and a point which it passes through it is possible to obtain the equation of the line from the of the slope-intercept form:

Where:

From the graph provided by the problem we can extract the two points we need.

Let:

Thus:

Now that we know the slope and the equation of the graph, we can easily find the y-intercept of the line. Actually you can conclude what is the y-intercept just by looking the graph, as you can see, the line crosses the y-axis at the point (0,1). However, let's find it using the equation that we found. As you may know, the line will cross the y-axis when x=0, so let's evaluate the function for x=0:

Therefore, the y-intercept of the line is (0,1).

38.5

step-by-step explanation:

lets say, first number = r

second number = 3r+7

total = 49

(r)+(3r+7)= 49

4r+7 = 49

4r = 42

r = 42/4

r= 10.5

3r+7 = 3(10.5)+7 = 38.5

hope this

18

step-by-step explanation:

draw the shape and you will see that f and k are actually at adjacent vertices (points of the hexagon that are neighboring).   so find the distance between (1,2) and (4,2).   that is easy since (1,2) and (4,2) is just a vertical distance to count, which is 3.   it is a regular polygon which means all sides are congruent.   you have 6 sides (hexa) so multiply 6 by 3 to receive 18.
