Question

Find the gradient and the coordinates of the y - intercept for the graph: y= 4 + 2x

Answer 1

y = 2x + 4 is in the form of y = mx + b, where m is the gradient and b is the y-intercept.

y = 2x + 4
y = mx + b

m = gradient = 2
b = y-intercept = 4

The gradient is 2.
The y-intercept is 4.

Answer 2

Well gradient means "slope" I just found out from searching the web.
First let's put y = 4 + 2x into slope intercept form of y = mx + b
y = 2x + 4
"m" is the slope, in this equation it would be 2.
The slope or "gradient" is 2.

The y-intercept of any equation in slope intercept form is the value of "b"
In this equation, the y-intercept is 4.
