Given triangle ABC with vertices A(16,0), B(9,2), and C(2,0).
Margaret [11]
Given:

Triangle Point coordinates or vertices:
A(16,0)
B(9,2)
C(2,0)

Required:

Side with slope -2/7

Solution:

To know which side has the slope required, we need to calculate the slope of each paired point by the two-point slope formula:

m = (y2-y1)/(x2-x1)

We first try points A and B.

m1 = (2-0)/(9-16)

m1 = -2/7

Thus, the side with the slope -2/7 is side AB.

katen-ka-za [31]

Answer:

y = 2x+7

Step-by-step explanation:

This is equation is in the form

y= mx+b  where m is the slope and b is the y intercept

y =2x + ?  means we are looking for the y intercept which is the value of y when x is zero

From the table, x=0 and y=7

y = 2x+7
