y = -5x + 6 .................1

y = -3x - 2......................1

first equate the two equations to find x and y

-5x + 6 = -3x - 2

-5x +3x = -2 - 6

-2x = -8

x = -8/-2

x = 4

Next substitute x in equation 1

y = 5(4) + 6

y = 20 + 6

y = 26

Graphically,

y = -5x + 6

for x = 0

y = -5 x 0 + 6

y = 6

for y = 0

0 = -5x + 6

5x = 6

x = 6/5

x = 1.2

fiirst plot the coordinate (0,6) and (1.2,0) on the graph for the first equation to get the first straight line.

y = -3x - 2

x = 0

y = -3 x 0 - 2

y = -2

y = 0

0 = -3x - 2

3x = -2

x = -2/3

x = -0.67

plot the coordinate on the graph

solution for this question is (4,26)
