write an equation using point slope form of the line having the given slope that contains the given point. m =3 and the point (-2, 1)

y=3x +7 slope intercept form

y=mx +b

y-1=3 x (x+2)   point slope form

Step-by-step explanation:

d) 30 units^2

area of rectangle = l × b

we know,

length = 10 unit

breadth = 3 unit

applying the formula,

= l × b

= 10 × 3

= 30 unit^2
