What is the location of the point on the number line that is 4/7 of the way from a = 4 to b = 18?
Sever21 [200]

Answer:

B) 12

Step-by-step explanation:

The difference between a and b = 18 - 4 = 14 units

4/7 of this difference = (4/7) x 14 = 8

the location of the point is hence the value at "a" plus 4/7 of the difference

= 4 + 8

= 12

Graph the line y = kx +1 if it is known that the point M belongs to it: M(1,3)
tigry1 [53]

Answer:

M(x,y) = (1,3) belongs to the line y = 2\cdot x +1. Please see attachment below to know the graph of the line.

Step-by-step explanation:

From Analytical Geometry we know that a line is represented by this formula:

y=k\cdot x + b

Where:

x - Independent variable, dimensionless.

y - Dependent variable, dimensionless.

k - Slope, dimensionless.

b - y-Intercept, dimensionless.

If we know that b = 1, x = 1 and y = 3, then we clear slope and solve the resulting expression:

k = \frac{y-b}{x}

k = \frac{3-1}{1}

k = 2

Then, we conclude that point M(x,y) = (1,3) belongs to the line y = 2\cdot x +1, whose graph is presented below.
