Question

Write the gradient and y-intercept of the following line: y=4x-5

Answer 1

Answer:

Y=4x-5

Y+x=4-5

-1xy

This is y volue

Answer 2

Step-by-step explanation:

The y-intercept is

−

5

.

The x-intercept is

5

4

.

Explanation:

y

=

4

x

−

5

is in the form of the slope-intercept formula for a linear equation,

y

=

m

x

+

b

, where

m

is the slope and

b

is the y-intercept.

By definition, the y-intercept is

−

5

.

To find the x-intercept, make

y

equal to zero and solve for

x

.

0

=

4

x

−

5

Add

5

to both sides.

5

=

4

x

Divide both sides by

4

.

5

4

=

x

Switch sides.

x

=

5

4

The x-intercept is

5
