Rite an equation of the line given its slope, m=-3, and its y-intercept, b =10.

y = -3x + 10

Step-by-step explanation:

What is x-intercept? It is such an argument (x-value) where y-value equals 0. In equations you would tell that it is root of the equation.

In general formula  y = m x + b  you insert known information, where  m  is a slope (or gradient) and  b  is free-term (or y-intercept - such an value where function cuts y-axis, so point (0, b) ).

Let us take example. You are given slope - it is 2. And you know that your x-intercept is equal 3. Therefore, you know that when  x = 3 ,  y = 0 .  

Let us use that information. You know that you may write every linear function like that:  y = m x + b .

Let us insert values:  0 = 2 ⋅ 3 + b

Our unknown is  b , free term. Let us isolate it:  b = − 6 .

And after all, we must insert our  b  value back into equation:  y = 2 x − 6 .

b. an equilateral triangle inscribed in a circle

step-by-step explanation:

we are given the figure of two circles having a triangle inside.

now, we know that,

"when a figure is lying inside an another figure, then the outside figure is known as circumscribed figure and the figure lying inside is referred to as the inscribed figure".

as we see that, the circles are containing the triangle completely.

thus, the circles are the circumscribed figures and the triangle is the inscribed figure.

hence, we get, 'an equilateral triangle is inscribed in a circle'.
