Y=2x+6 We know the y intercept is +6 so we still can’t eliminate any of the options. We know it can’t be 1/3x or 1/2x because the y value is greater than the x value. (6)(2)+6=18
Answer:
1.7
Step-by-step explanation:
( 5x + 2y = 7 ) 2
( - 2x + 6y = 9 ) 5
10x + 4y = 14
-10x + 30y = 45
----------------------
34y = 59
y = 1.7

Answer:</h3>
y = 8/9x + 80/9
<h3>
Step-by-step explanation:</h3>
<u>We are given;</u>
- Equation of a line as 8x -9y -2 = 0
- Coordinates (-1,8)
We are required to determine the equation of a line parallel to the given line and passing through a point (-1,8)
<h3>Step 1: Determine the Gradient of the given line </h3>
- When an equation is written in the form y = mx + c, m is the gradient.
- Therefore; we could write the equation 8x -9y -2 = 0 in the form of y= mx + c
9y = 8x -2
y = 8/9x - 2/9
Therefore, the slope, m = 8/9
<h3>Step 2: Determine the equation of the line</h3>
- We need to know that parallel lines have the same gradient
- Therefore, the slope of the line in question is 8/9
- It passes through a point (-1, 8)
We can therefore, determine the equation;
Taking another point, (x,y)

9(y-8) = 8(x+1)
9y - 72 = 8x + 8
9y = 8x + 8 +72
9y = 8x + 80
y = 8/9x + 80/9
Therefore, the equation of the line is y = 8/9x + 80/9
D is the answer so u have to add and to make 7.5 a decimal u move it 2 places to the left
