Answer:
Step-by-step explanation:
The question lacks appropriate diagram. Find the diagram attached.
Slope is the change in coordinate of the y coordinate to the x coordinate.
Mathematically, slope m = ∆y/∆x
From the diagram ∆y is the same as 3 (along the vertical) while ∆x is the same as 1 (along the horizontal)
m = ∆y/∆x = 3/1
∆y/∆x = 3/1
y/x = 3/1
Cross multiply
y × 1 = 3 × x
y = 3x
Hence the slope of the line is y = 3x
We have that
x²<span>+2x=17

the square. Remember to balance the equation
</span>(x²+2x+1)=17+1
Rewrite as perfect squares
(x+1)²=18
x+1=(+/-)√18
x=(+/-)√18-1
x1=√18-1----> 3.24
x2=-√18-1----> -5.24
