Gloria is categorizing triangles based on their properties. The side lengths of the triangles are listed below. Triangle 1: 3 cm, 4 cm, 5 cm Triangle 2: 5 cm, 5 cm, 7 cm Triangle 3: 6 cm, 7 cm, 9 cm Triangle 4: 8 cm, 8 cm, 8 cm She places the triangles into 3 different groups: scalene, isosceles, and equilateral. Which pair of triangles would Gloria put in the same group? A. 1 and 2 B. 1 and 3 C. 2 and 3 D. 2 and 4

(d)

step-by-step explanation:

given: the line in the graph passes through points (5,30) and (6,26).

then, the equation of line is:

now, put y=a(n) and x=n,

hence, option d is correct.

step-by-step explanation:

let

we know that

the y-intercept is the y-coordinate of the point when the value of x is equal to zero

so

the y-coordinate of the point a is the y-intercept

the answer part a) is

the value of y-intercept is

part b) find the slope m

we know that

the value of the slope is equal to

substitute the values

therefore

the answer part b) is

the value of the slope is equal to

the general answer is

the slope is

the value of y-intercept is
