Write the equation 'x-intercept = 4, y-intercept = -1' in slope-intercept form.

y = 1/4x-1

Step-by-step explanation:

The slope intercept form of a line is

y = mx+b

m is the slope and b is the y intercept

but we do not know the slope y know the x intercept

(4,0 )

and  the y intercept

( 0,-1)

We can calculate the slope  using these points

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

   = (-1-0)/(0-4)

    = -1/-4

    = 1/4

Now we can put the slope = 1/4 and the y intercept =-1 into the formula

y = 1/4x-1

pentagon

step-by-step explanation:

the coordinates   a(5, -2), b(3,-1),c(-4,-4) d(-3,8) and e(-1,4) forms the vertices of the polygon when they are connected in order.

in order to classify that which polygon is it with the given coordinates, first count the number of vertices and then count the number of sides it can make with these vertices.

since, the given coordinates have five vertices, therefore, it will make five sides. moreover, pentagon is regular in nature therefore it will be convex.

now, a polygon with five sides is known as pentagon, therefore, the given polygon is the pentagon.
