Write the equation of a line that goes through the points (1,-1) and (3,2).

y=3/2x-5/2

Step-by-step explanation:

1.find the slope

y2-y2/x2-x1

2-(-1)/3-1

2+1/3-1

3/2 slope (m)

2.y-y1=m(x-x1)

y-(-1)=3/2(x-1)

y+1=3/2x-3/2

y=3/2x-3/2-1

y=3/2x-5/2

126.66 m²

step-by-step explanation:

the pertinent area formula is a = πr², where r is the radius.

here, a = π(6.35 m)² = 40.32π, or approximately 126.66 m²

the graph in the attached figure

step-by-step explanation:

we have

using a graphing tool

the graph in the attached figure

the roots are ( x-intercepts) x=-0.5,x=1,x=3

the y-intercept is the point (0,3)
