Answer:
y-3 = 4(x+2) point slope form
y = 4x+11 slope intercept form
Step-by-step explanation:
Since we have a point and a slope, we will start with point slope form
y-y1 = m(x-x1)
y-3 = 4(x--2)
y-3 = 4(x+2)
This is point slope form
Distribute
y-3 = 4x+8
Add 3 to each side
y-3+3 = 4x+8+3
y = 4x+11
slope intercept form
Answer:
Point slope form:y-3=4x+2
slope intercept form: 4x + 11 = y
Step-by-step explanation:
(-2,3)
-2=x1
3=y1
m=4
(y - y1) = m(x - x1)
-point slope form equation
(y - (3)) = 4(x - (-2))
- substitute values
y-3=4x+2-simplified equation
slope intercept:(to find intercept of slope you need to know where the slope begins)
find "b" first in y=mx+b:
and y1 as "y"
take(x1) as "x"- this is because (-2,3) is an x,y pair and we have an x and an y in "y=mx +b"
(3)=4(-2)+b
3=-8+b
add "8" to both sides
3+8=-8+8+b
11=b
since we know be we can solve for the y intercept in "y=mx+b"
y=4x+11-this is the "y" intercept
so slope intercept form= y=4x+11
hope this helps
