So youre a given two points. The points (0,15) and (150,0). First
solve the slope of the graph
M = (y1 – y2) / (x1 – x2)
M= (15 – 0) / ( 0 – 150)
M = - 0.1
Using point (15,0)
15 = -0.1(0) + b
15 = b
So y = mx + b
Y = -0.1x + 15
<span>-14 x 8 x 1/4 + (-22)
Apply BODMAS
Open the brackets:
</span>-14 x 8 x 1/4 + (-22) = <span>-14 x 8 x 1/4 -22
Division
-14 x 8 x (1/4) - 22 = </span><span>-14 x 8 x 0.25 - 22
</span><span>
Multiplication
</span><span>(-14 x 8 x 0.25 )- 22 = -28 - 22
</span><span>
Subtraction
-28-22 = -50
Correct answer: A <-50>

5x = 2 + 6y
Divide both sides by 5
x = 6/5y + 2/5
Input in the other equation.
2.4 = .3(6/5y + 2/5) + .4y
2.4 = .36y + .12 + .4y
2.4 = .76y + .12
Subtract .12 from both sides.
2.28 = .76y
Divide both sides by .76
3 = y
x = 6/5(3) + 2/5
x = 18/5 + 2/5
x = 20/5 = 4
