Answer:
Step-by-step explanation:
In the equation y=kx+1, k is the slope and 1 is the y-intercept.
To find the slope, use the formula k=y2-y1/x2-x1. To use this formula, you need two points. The first point, point M, is given to you. The second point can be the y-intercept, point (0, 1). Now, apply the formula to find the slope: k=3-1/1-0
k=2/1
k=2
We now have the equation y=2x+1.
The next step is to graph the line.
First, graph the y-intercept. Should look something like this: (star represents point. the point is on (0, 1).)

Then, use the slope to find your second point: (the point is on (1, 3)).

Draw a line through those two points and you have your answer!
Answer:
12, 4, 24, 30, and 14 are the answers
X = dryer
(X+79) = washer
X + (X+79) = $1029
Therefore, x+x+79= 1029 or 2x+79=1029
Solve for x
2x = 1029-79
2x = 950
2x/2 = 950/2
X= $475 The price of the dryer is $475
To set up this equation you create 14x+12y=314 is equal to 7x+11y-247 (the x representing the number of blue berries, and y representing the number if blackberry pies. In the end.
