Add 7 to both sides
Y+7=3
Divide both sides by 3
Y+7/3=x
Switch sides
X=y+7/3
To find the x-intercept you must make y=0
3x+2y=12 - substitute 0 for y
3x+2(0)=12 - multiply 2 and 0
3x+0=12 - add zero
3x=12 - divide by 3
x=4
To find the y-intercept you must make x=0
3x+2y=12 - substitute 0 for x
3(0)+2y=12 - multiply 3 and 0
0+2y=12 - add 0 and 2y
2y=12 - divide by 2
y=6
Answer:
Step-by-step explanation:
A(7,1), B(5,-6)
(AB)² = (-6-1)² + (5-7)² = 53
AB = √53
Answer:
5,3
Step-by-step explanation:
5*3=15
15*3=45
Answer:
x = -1
Step-by-step explanation:
because both lines intersects at -1.
