Answer:
y = 3x-16
Step-by-step explanation:
We know the slope and a point , so we can use the point slope form of the equation for a line
y-y1 = m(x-x1) where the slope is m and the point is (x1,y1)
y--1 = 3(x-5)
y+1 = 3(x-5)
We need to rearrange the equation into slope intercept form y=mx+b
First distribute the 3
y+1 =3x-15
Then subtract 1 from each side
y+1-1 =3x-15-1
y = 3x-16
This is in slope intercept form
The point-slope form:
[tex]y-y_1=m(x-x_1)[/tex]
m - slope
(x₁, y₁) - point
We have the slope m = 3 and the point (5, -1). Substitute:
[tex]y-(-1)=3(x-5)\\\\y+1=3(x-5)[/tex]
Convert to the slope-intercept form: [tex]y=mx-b[/tex]
[tex]y+1=3(x-5)[/tex] use distributive property a(b + c) = ab + ac
[tex]y+1=3x-15[/tex] subtract 1 from both sides
[tex]\boxed{y=3x-16}[/tex]
