Question

Which is an equation in point-slope form for the given point and slope?

 

Point: (–3, 7); Slope: 4

anonymous · Answer

y=mx+c

anonymous · Answer

y=mx+b
we know slope so m=4 and we know the x and y coords so x=-3 and y=7
y=mx+b
7=4(-3)+b
7=-12+b
7+12=b
b=19
therefore
y=4x+19

anonymous · Answer

A.
	

y – 7 = 4(x – 3)
	
 
B.
	

y – 7 = 4(x + 3)
	
 
C.
	

y + 7 = 4(x + 3)
	
 
D.
	

y + 7 = 4x – 12

all man

gorv · Answer

y-7=4(x+3)

gorv · Answer

y-y1=$$y-y1=\frac{ y2-y1 }{ x2-x1 }*(x-x1)$$

gorv · Answer

it is point slope form

gorv · Answer

$$\frac{ y2-y1 }{ x2-x1 } is slope here$$

gorv · Answer

as we already have slope =4 so no need to go for slope
and (x1,y1 ) are (-3,7)   @zobobozo
