<span>The equation of the linear function is given in the form of a directional
</span><span>equation consists of solid :
1.współczynniki a and b .
2. The variables x and y
</span>y= 3x - 12
y = ax + b
a = 3 (<span>the slope of the tangent to the x-axis)
</span>b = - 12 (<span>intersection of the axis y)
</span>we look for the point ( 0 , -12 ) because b = -12
A. (4, 0) ,(0, -12)
