What is the slope of the line that contains these points?

Mathematics

Answer:

8.

Step-by-step explanation:

The slope =

difference in y coordinates of 2 points / difference in coordinates of corresponding x coordinates.

So taking the first 2 points:

The slope =  (18-10) / 0 - (-1)

= 8/1

= 8.

This is confirmed by slope between the second and third points

slope = 26-18/ (1-0) = 8.

#1: Write the equation of the graphed line. NO SPACES, ALL LOWERCASE. <br> Please help
ivanzaharov [21]

Answer:

Equation of graphed line is \mathbf{y=\frac{2}{3}x-3}

Step-by-step explanation:

We need to write the equation of the graphed line.

The equation will be in slope intercept form y=mx+b where m is slope and b is y-intercept

We need to find slope and y-intercept.

Finding slope

Slope can be found using formula: Slope=\frac{y_2-y_1}{x_2-x_1}

We will use points (0,-3) and (3,2)

Looking at the graph, we get x_1=0, y_1=-3, x_2=3, y_2=-1

Putting values in graph and finding slope

Slope=\frac{y_2-y_1}{x_2-x_1}\\Slope=\frac{-1-(-3)}{3-0}  \\Slope=\frac{-1+3}{3}  \\Slope=\frac{2}{3}

So, we get slope \mathbf{\frac{2}{3}  }

Finding y-intercept

y-intercept can be found when x is zero.

So, looking at graph, when x =0, y=-3

So, y-intercept is -3

Equation of Line

So, equation of line having slope \mathbf{\frac{2}{3}  } and y-intercept b = -3

y=mx+b\\y=\frac{2}{3}x-3

So, Equation of graphed line is \mathbf{y=\frac{2}{3}x-3}
