Answer:
C.
Step-by-step explanation:
All we need to create an equation of the given graph is a point on the line (x1, y1) and the slope (m) of the line.
Thus, equation of in point-slope form is given as .
Finding the slope (m) of the line of the graph given, using points (0, 1) and (1, -2).
Substitute (x1, y1) = (1, -2) and m = -3 into
The answer is C.
Answer:
y=x+15
Step-by-step explanation:
1. find the slope
m=(24-19)/(9-4)
m=5/5
m=1
2. plug slope into slope intercept formula
y=1x+b
y=x+b
3. plug in for x and y from either coordinate point (just make sure they are from the same point!!)
24=9+b
15=b
4. plug m and b into formula
y=x+15
Answer:
x = -16, y = -10, z = 7
Step-by-step explanation:
z = 7
y+2z = 4
Substitute z=7
y +2(7) = 4
y +14=4
Subtract 14
y +14-14 = 4-14
y = -10
x-y+5z = 29
Substitute z=7 and y = -10
x - (-10) + 5(7) = 29
x+10 +35 = 29
x +45 = 29
Subtract 45
x = 29-45
x =-16
