Lis parallel to y=5x. write an equation for line l in point-slope form

Point slope is y - Y=m(x-X)  where m is slope and (X,Y) is a given point on the line

so you can get y-Y= 5(x-X) 
and then just choose a point for your parallel line to go through, say (2,3)

so you get y-3 = 5(x-2)

Answer: d. 39 cmin the diagram, the approximate length of the minor arc de is 39 centimetres.step-by-step explanation: the formula for the length of an arc in a circle is as displayed below.let the length of the minor arc de = xx = 2( pi )r × angle of sector / 360°from this, we will substitute the values given from the problem into the formula to obtain the length of the minor arc de.x = 2( pi )r × angle of sector / 360°r = radius = 25cmpi as an approximate value = 3.14angle of sector = 120°x = 2( 3.14 )( 25 ) × 120° / 360°x = 157 × 1 / 4x = 39.25x = 39 ( rounded to the nearest whole number as an approximate value )
