Answer:
22
Step-by-step explanation:
We will be using y = mx + b
m would be the slope
b would be the cut point with the y-axis (aka the y-intercept)
We will take y-1=-7(x-3) into the form of y = mx+b
- x - would be +
y-1= -7x + 21
Take the -1 from the left side to the right side
y = -7x + 21 + 1
y = -7x + 22
b would be 22
The fact that I recently finish with this work a while ago with my teacher.
Hope this helps.
Hey there!
In order to identify the y-intercept of the line, we should first convert the equation of the line (which is written in point-slope form), into slope-intercept form (y=mx+b)
So, let's do it. :)
y-1=-7(x-3)
Distribute -7:
y-1=-7x+21
Add 1 to both sides:
y=-7x+21+1
y=-7x+22
Hence, the y-intercept is

Hope everything is clear.
