How do I graph this equation? y = 4x + 1? Can someone tell me step by step?

Answer 1

Plott a Cartesian Plane, then find x and intercept.

An x-intercept is a pointon the graph where y is zero.

An y-intercept is a pointon the graph where x is zero.

In tis case:

x-intercept

0 = 4 x + 1

Subtract 1 both sides

- 1 = 4 x

Divide both sides by 4

- 1 / 4 = x

x = - 1 / 4

Coordinate of x-intercept:

x = - 1 / 4 , y = 0

You can write that like ( - 1 / 4 , 0 )

y-intercept

y = 4 ∙ 0 + 1

y = 1

Coordinate of y-intercept:

x = 0 , y = 1

You can write that like ( 0 , 1 )

In a Cartesian Plane mark points ( - 1 / 4 , 0 ) and ( 0 , 1 ) then draw straight line.
