The one which shows a straight line with a positive gradient of 3 and crossing the y axis at 2.
A linear equation ?

It represents an algebraic equation in the variable, k.
ax + by = cThe graph if that equation is a straight line whose slope is (-a/b)and whose y-intercept is (c/b).
y=-10x-4
The slope of the line that represents the graph of that equation is 15.
-2x plus 3y equals 1
y = -0.5x plus or minus any number
A linear equation ?
Same way you graph y = -4x - 0.5
That's not an equation, so there's nothing to graph. Simple way to tell: There's no "equals" sign in it.
answer is 1
That is the standard equation to graph a line.
y=6
the graph is moved down 6 units
