Answer:
Step-by-step explanation:
-a + 6b = -3 + 6 * (-6) = -3 - 36 = -39
If you solve this problem using the substitution method then,
X = - 8
Y = - 4
Answer:
y=3x+2
Step-by-step explanation:
First find the slope or m in the line of equation y=mx+b
to find slope you need two points, plug in to y2-y1 / x2-x1
so lets use points (0,2) (1,5)
5-2 / 1-0 = 3
m=3
we have y=3x + b
now we find b by pugging in a point, let's use (0,2)
2 = 3(0) + b
b= 2
y=3x+2
