# Co-aontaran agus eas-aontaran test questions

### 1

Obraich a-mach co-aontar na loidhne dhìrich, a tha a' dol tron phuing (0,-7) le caisead de 4, san riochd $$y = mx + c$$.

### 2

Obraich a-mach co-aontar na loidhne a tha a' dol tro na puingean C(0,-1) agus D(2,3).

### 3

Obraich a-mach caisead na loidhne dhìrich le co-aontar $$4y - 8x - 1 = 0$$.

### 4

Obraich a-mach caisead na loidhne dhìrich a tha co-shìnte ris an loidhne aig a bheil an co-aontar $$2y - x + 4 = 0$$.

### 5

Obraich a-mach caisead na loidhne dhìrich a tha a' dol tro na puingean P(-1,1) agus Q(5,13).

### 6

Obraich a-mach co-aontar na loidhne dhìrich a tha co-shìnte ri $$2y = 3x - 7$$ agus a tha a' dol tro (0.5, -1).

### 7

Fuasgail an co-aontar: $$6x + 15 = 4x + 17$$

### 8

Fuasgail an co-aontar: $$3(8 - x) + 1 = x + 5$$

### 9

Fuasgail an t-eas-aontar: $$5y - 16 \ge y + 32$$

### 10

Fuasgail na co-aontaran co-amail seo:

$3x + y = 7$

$3x - y = 5$

### 11

Fuasgail na co-aontaran co-amail seo:

$3x + 2y = 4$

$2x + y = 3$

### 12

Fuasgail na co-aontaran co-amail seo:

$5x + 2y = 20$

$x + 4y = 13$

### 13

Atharraich cuspair an fhoirmle gu t.

$C = k{t^2}$

### 14

Atharraich cuspair an fhoirmle gu $$a$$.

${L^2} = {a^2} + {b^2}$

### 15

Atharraich cuspair an fhoirmle gu $$h$$.

$A = \sqrt {\frac{{hw}}{{3600}}}$
