Answer:
y-7=3(x-9)
Step-by-step explanation:
It appears they want your answer in point-slope form, which is identified by the equation y-y1=m(x-x1)
Step 1: Find the slope (m)
m=(y2-y1)/(x2-x1)
m=(-8-7)/(4-9)
m=(-15)/(-5)
m=3
The slope is m=3
Step 2: Plug in m, y1, and x1
y-y1=m(x-x1)
y-7=3(x-9)
Therefore our final equation is y-7=3(x-9)

Answer:
The slope intercept form of both given equations is : y = - 3 x - 4.
Step-by-step explanation:
Here, the given equations are:
y +7 = -3 ( x - 1 )
and 3 x + y = - 4
Now,the SLOPE INTERCEPT FORM of any given equation is given as:
y = m x + C : here, C = Y - intercept, m = Slope
Consider equation (1):
y +7 = -3 ( x - 1 ) ⇒ y + 8 = - 3 x + 3
or, y = -3x + 3 - 7 = -3x - 4
⇒ y = -3x -4
Hence, the slope-intercept form of the given equation is y = -3x -4.
Consider equation (2):
3 x + y = - 4 ⇒ y = -4 - 3 x
⇒ y = -3 x - 4
Hence, the slope-intercept form of the given equation is y = -3x -4.
