Answer:

3. Option 2 (Perpendicular)

4. Option 3 (neither)

Step-by-step explanation:

m1 = -7/8

Second equation: -8x + 7y = -21

7y = 8x - 21 y = (8/7)x - 3

m2 = 8/7

m1 & m2 are not equal, so not parallel

Since m1×m2 = (-7/8)(8/7) = -1,

They are Perpendicular

m1 = -1/4

Second equation: -2x + 8y = 6

8y = 2x + 6 y = (1/4)x + 3/4

m2 = 1/4

m1 & m2 are not equal, so not parallel

Since m1×m2 = (-1/4)(1/4) = -1/16, not -1. They are not Perpendicular either. So, neither

Answer:

The gradient of the graph below is $\mathbf{\frac{3}{2} }$

Step-by-step explanation:

We need to calculate the gradient of the graph

The gradient of graph is actually slope of the graph.

The slope of graph can be calculated using formula: $Slope=\frac{y_2-y_1}{x_2-x_1}$

Taking any 2 points on graph i.e

(1,0) and (-1,-3)

We have $x_1=1, y_1=0, x_2=-1,y_2=-3$

Putting values and finding gradient:

$Slope=\frac{y_2-y_1}{x_2-x_1}\\Slope=\frac{-3-0}{-1-1}\\Slope=\frac{-3}{-2}\\Slope=\frac{3}{2}$

So, The gradient of the graph below is $\mathbf{\frac{3}{2} }$
