Answer:
y = - 2x + 3
Step-by-step explanation:
the equation of a line in gradient- intercept form is
y = mx + c ( m is the gradient and c the y- intercept )
given the equation
30y + 60x - 90 = 0 ( subtract 60x from both sides )
30y - 90 = - 60x ( add 90 to both sides )
30y = - 60x + 90 ( divide through by 30 )
[tex]\frac{30}{30}[/tex] y = [tex]\frac{-60}{30}[/tex] x + [tex]\frac{90}{30}[/tex] ( simplify both sides )
y = - 2x + 3 ← in gradient- slope form
