Slope intercept form:
y = mx + b
Where m = slope and b = y-intercept.
By looking at the graph, we can see that the line cuts at 1/2 on the y-axis, therefore eliminating option D.
So now we have:
y = mx + 1/2Next, we'll find the slope.

Plug the coordinates into the formula.

So our slope is 5/8 and the y-intercept is 1/2.
Option A is the answer.
Answer:
0.000000014
Step-by-step explanation:
1.4 ×
=
= 0.000000014
Note that if we add each side of the 2 equations, y will cancel out:
-12x-y+(17x+y)=6+4
5x=10
x=2
Substituting x=2 in either of the equations, we find the value of y.
Let's use the first equation:
-12x-y=6
-24-y=6
-y=24+6
-y=30, so y=-30.
Thus, the solution is (2, -30)
Answer: C
Answer:
1.8m²
Step-by-step explanation:
∅= 51× π/180 = 17π/60
area of sector= 1/2 × r²× ∅
= 1/2 × 2²× 17π/60
= 34π/60
= 1.78m²
X-y=5
x times y= 84
-7 and -12
