It’s linear so you map out the first differences and then put it into y=Mx+b form. For the you gotta find the y intercept

Let's find the slope (m) :

  • \dfrac{y2 - y1}{x2 - x1}

  • \dfrac{16 - 11}{9 - 6}

  • \dfrac{5}{3}

slope of given line is 5/3

now, let's plug the value of coordinates of a point lying on the line ( for example : (6 , 11) and slope (m) to find the y - intercept (c) :

  • y = mx + c

  • 11 =   \bigg(\dfrac{5}{ 3}  \times 6 \bigg)  + c

  • 11 = (5 \times 2) + c

  • 11 = 10 + c

  • c = 11 - 10

  • c = 1

value of y - intercept (c) = 1, so our equation will be :

  • y = mx + c

  • y =  \dfrac{5}{3}x  + 1

The parallelogram shown below has an area of <br> 20 units squared. Find the missing base
valkas [14]

Answer: 5 units

Step-by-step explanation:

The area of a parallelogram is A=bh. SInce we know the area and the height, we can directly plug the values into this equation and solve for the base.

20=b(4)         [divide both sides by 4]

b=5 units
