(0,0) cannot help prove the values of y=4x because you cant confirm the gradient and it certainly wont help you confirm whether there's no intercepts.

Y varies directly as the square of x. When x = 5, y = 100. Find y when x = 6.

loris [4]

Let be x=5, so y=100= 5² *4=5²*2²=100
so if x=6, so y=6²*2²=36*4=144
the answer is <span>y = 144</span>

select the equation of the line that passes through the point (3,-1) and is parallel to the line on the graph

blagie [28]

ANSWER

y=-1

EXPLANATION

The given line in the graph has equation

$y = 2.5$

This line is a horizontal line.

All horizontal line has a slope of 0.

Let the equation of the line that is parallel to this line be

$y = mx + b$

The slope of this line must also be zero.

We substitute the slope, m=0 and the point (3,-1) into this equation to get:

$- 1 = 0(3) + b$

$\therefore \: b = 0$

Hence the required equation is

$y = - 1$
