Find the slope given the points (-5,-3) and (2,4)
Setler79 [48]

Answer:

The slope of the line is 1.

Step-by-step explanation:

We are given two coordinate points:

  • (-5, -3)
  • (2, 4)

We can use the rate of change formula to find the slope of the points.

  • \displaystyle \frac{\triangle y}{\triangle x}

In mathematics, coordinate pairs are labeled as:

(x_1, y_1) \ \text{and} \ (x_2, y_2)

Therefore, we can relabel our points:

  • x_1 = -5
  • y_1 = -3
  • x_2 = 2
  • y_2 = 4

After we do this, we can expand the rate of change formula:

\displaystyle m = \frac{y_2-y_1}{x_2-x_1}

Now, we can use simple substitution to solve for m, or the slope.

\displaystyle m = \frac{y_2-y_1}{x_2-x_1}\\\\m = \frac{4-(-3)}{2-(-5)}\\\\m = \frac{7}{7}\\\\m = 1

Therefore, the slope of the line is 1.

Write an exponential function for the graph that passes through the points (0,4) and (2, 36). Use the formula y=ab^x​
fomenos

Answer:

Using the equation y = abx , substitute both of your given points into that equation.

2 = ab2 and 4 = ab3   Solve each equation for a.

2⁄b2    and 4⁄b3 = a     Therefore, 2⁄b2 = 4⁄b3

                                   

Cross multiply: 2b3 = 4b2     Divide both sides by b2

2b = 4      a = 2/4 = 1/2

b = 2

y = 1 (2)x

     2
