6+ 4/5b= 9/10b
⇒ 6= 9/10b -4/5b
⇒ 6= 1/10b
⇒ 6/(1/10)= b
⇒ 6*(10/1)= b
⇒ 60= b

Final answer: b= 60~

Find the distance between points (1, 2) and (5, 9). Show all work.

To calculate the distance between two points, we can use a formula that is a variation Pythagorean Theorem. Look:

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

"d" represents the distance and coordinates are expressed as follows: (x, y)

Let's go to the calculations.

$\mathsf{d=\sqrt{(x_2-x_1)^2+(y_2-y_1)^2}}\\\\ \mathsf{d=\sqrt{(5-1)^2+(9-2)^2}}\\\\ \mathsf{d=\sqrt{(4)^2+(7)^2}}\\\\ \mathsf{d=\sqrt{16+49}}\\\\ \mathsf{d=\sqrt{65}}\\\\ \mathsf{d=8.06225774829854...}\\\\ \underline{\mathsf{d\approxeq8.06}}$

The answer is 8.06 uc.

Anya graphed the line (y – 2) = 3(x – 1) on the coordinate grid. The slope of her line is .

Ur equation is in this form : y - y1 = m(x - x1)....in this form , point slope form, the slope can be found in the m position.

y - 2 = 3(x - 1)
y - y1 = m(x - x1)

so u see, the slope (the number in the m position) = 3
