Answer:

[1, 4]; 1 = m

Step-by-step explanation:

According to the Point-Slope Formula, <em>y - y₁ = m(x - x₁)</em>, all the negative symbols give the OPPOSITE terms of what they really are, so in this case, the coordinates are [1, 4]. Now, the <em>rate</em><em> </em><em>of</em><em> </em><em>change</em><em> </em>[<em>slope</em>] is <em>1</em><em> </em>because an invisible coefficient is always assumed to be <em>1</em><em>.</em>

Answer:

The slope of the line is 1 and it passes through the point (1,4).

Step-by-step explanation:

If a line passes through a points (x_1,y_1) with slope m, then the point slope form of the line is

y-y_1=m(x-x_1)            .... (1)

The given equation of line is

y-4=(x-1)                .... (2)

We need to find the slope and the coordinates of a point on the given line.

On comparing (1) and (2) we get

m=1

x_1=1

y_1=4

Therefore, the slope of the line is 1 and it passes through the point (1,4).

PLEASE HELP!!!!!<br> will mark brainliest!!!!!
zmey [24]

Answer:

Table:

1: f(x) = 5

2: f(x)= 6

5: f(x) = 9

Points: (1,5), (2,6), and (5,9)

Step-by-step explanation:

1. The function f(x) = x + 4 means that 4 is added to the input, x, to get the output, y.

  • f(x) = 1 + 4 = 5
  • f(x) = 2 + 4 = 6
  • f(x) = 5 + 4 = 9  

Therefore, when x = 1 then f(x) = 5, x = 2 then f(x) = 6, and x = 5 then f(x) = 9.

2. Now, to find the points, we must know that x is the x-coordinate and f(x) is the y-coordinate of the point. Because of this, the points are:

  • (1,5)
  • (2,6)
  • (5,9)

Therefore, the points are (1,5), (2,6), and (5,9).

The coordinates of AB are A(-4,4) and B(2,1) which measurement is closest to the length of AB units
vredina [299]

Answer:

AB\approx 6.7\ units

Step-by-step explanation:

<u><em>Distance between two points:</em></u> Distance between two points (x_1,y_1)\ and\ (x_2,y_2) is given by

d=\sqrt{(y_2-y_1)^2+(x_2-x_1)^2

A(-4,4)\ and\ B(2,1)\\\\AB=\sqrt{(1-4)^2+(2+4)^2}\\\\AB=\sqrt{(-3)^2+(6)^2}\\\\AB=\sqrt{45}\\\\AB=3\sqrt{5}\\\\AB\approx 6.7\ units
