Answer:
Y = 9X-29
Step-by-step explanation:
y = mx + b
P1 : ( 4 , 7 )
m = 9
using equation of line ,
y = mx + b
7 = ( 9 ) (4 ) + b
7 - 36 = b
b = -29 ,
hence equation of line is ,
y = 9x - 29 answer
Answer:
y - 7 = 9(x - 4)
Step-by-step explanation:
The equation of a line in point- slope form is
y - b = m(x - a)
where m is the slope and (a, b) a point on the line
Here m = 9 and (a, b) = (4, 7), thus
y - 7 = 9(x - 4) ← equation in point- slope form
