Answer:

x = 4, y = -10

Step-by-step explanation:

if both expressions equal 'y' then you can solve by setting them equal to each other:

-5x + 10 = -2x - 2

-3x + 10 = -2

-3x = -12

x = 4

find 'y':

y = -5(4)+10

y = -20 + 10

y = -10

A the slope of the line is 1

to calculate the slope m , use the ' gradient formula '

m = ( y₂ - y₁ ) /( x₂ - x₁ )

where (x₁, y₁ ) = 6, 3) and (x₂, y₂ ) = (9, 6)

m = $\frac{6 - 3}{9 - 6}$ = $\frac{3}{3}$ = 1
