Write down the gradient and y-intercept of each line y=4x - 1

y=
help pls

Equation of a line is y = mx + c

where m is the gradient

c is the y intercept

y = 4x - 1

Comparing with y = mx + c

The gradient = 4

y intercept = - 1

Comparing with y = mx + c

The gradient is 1/3

The y intercept is 3

Hope this helps you

4 and  -1

1/3 and 3

Step-by-step explanation:

for y=4x-1

y intercepts where  x=0 so f(0)=4*0-1=-1

y intecepts = -  1

the gradient is y2-y1/x2-x1 where y2=f(x2)=4x2-1 and y1=f(x1)=4x1-1

the gradient is 4x2-1-4x1+1/x2-x1=4 ( the coeficient of x)

for y=1/3x+3

the gradient is 1/3

y intercepts is f(0)=3

y = 2x

step-by-step explanation:

if you divide each number in the sequence, you'll see that they all have a multiple factor of 2. each number in the series, and any other numbers which may continue, will be multiplied by 2. therefore, y is the next number in the sequence, and x is the current one, so, our formula will be y = 2x.
