Answer: Y= -3/4x+13
Step-by-step explanation:
A line passes through the point (8,7) and has a slope of negative 3/4 Write an equation in slope-intercept form for this line.
This is what i get
Slope of a line Y= mx+b
Y= 7
X= 8
M= -3/4
7= -3/4(8)+b
7= -6+b
7+6=b
13=b
Y= -3/4x+13
Answer:
(2, -1)
Step-by-step explanation:
We can add the first equation by the second
(4x + 6y = 2)+(-4x + 4y = -12)=
10y=-10
we divide both sides by 10 to get
y=-1
We plug -1 in the second equation to get:
-4x+4(-1)=-12
-4x-4=-12
-4x=-8
Now, we divide both sides by -4
x=2
Hope this helps!
