Answer:

6x - 15y = -63

15x -15y = -90

Step-by-step explanation:

We need to multiply the two equations by a constant that will eliminate the y terms.

The two equations are:

2x - 5y = -21

3x - 3y = -18

Let us multiply the first by 3 and the second by 6. The resulting equations will be:

6x - 15y = -63

15x -15y = -90

Note: To solve the system of equations we can simply subtract the first from the second.

Can someone help me with (a) and (c)? Thanks! ;D
BaLLatris [955]

Answer:

Step-by-step explanation:

a) Mark any two points in line a

(0,7)  ; (5,-3)

Find the slope

slope = y2 - y1 /x2-x1

=\frac{-3-7}{5-0}\\\\=\frac{-10}{5}\\\\=-2

Equation: y-y1 = m(x-x1)

y - 7 = -2(x - 0)

y - 7 = -2x

y = -2x + 7    --------> line a

c) equation of line b

(2,-1);  slope = -2  {as b line is parallel to line a}

y - y1 =m(x-x1)

y -(-1) = -2*(x - 2)

y + 1 = -2x - 2*-2

y + 1 = -2x + 2

y = -2x + 2 -1

y = -2x +1   ------> equation of line b
