Bingel [31]

Answer:

Step-by-step explanation:

Slope (m) = 5

Y-intercept (b) = 7

Using the equation y=mx+b, you can find m and b to make y=5x+7.

Steps:

(1, 12) (2, 17) formula: y2-y1 / x2-x1 = m

17-12= 5

2-1 = 1

5/1=5

m=5

12=5(1)+b

12=5+b

7=b

17=5(2)+b

17=10+b

7=b

<u>Answer: y=5x+7</u>

<u>or</u>

<u>f(x)=5x+7</u>

Answer:

Step-by-step explanation:

Diagonals of a rhombus are perpendicular bisector.

Hence, triangle ABE so formed would be a right triangle right angled at E.

Therefore, by Pythagoras theorem:

$AB = \sqrt{AE^2 + BE^2 } \\ \\ \therefore \: AB = \sqrt{5^2 + 12^2 } \\ \\ = \sqrt{25 + 144} \\ \\ = \sqrt{169} \\ \huge \red { \boxed{ \therefore \: AB= 13}}$
