Y= 2x-4 is the slop-intercept form your'e looking for there isn't a lot of work include because you; re just plugging what you have in the equation y=bx+m

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

y = 2x-4  

the slope is 2

the y intercept is -4

Explanation:

Slope-intercept form: →

m: represents the slope and is constant.

b: represents the y-intercept.

The y-intercept is the point on a graph at which the graph crosses the y-axis.

You had to used rise/run.

But the slope is 2

But the y-intercept is -4.

Hope this helps!

Thanks!

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'.

hope to be marked brainliest
