If a triangle has all three angles equivalent and all three sides equivalent, what type of triangle is it 1. Equilateral
2. Obtuse scalene
3. Obtuse isosceles
4. Acute isosceles

1 and 4

Step-by-step explanation:

An Equilateral triangle has equal sides.

an Acute triangle has angles that are less than 90

linear pair postulates

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
