Question

The equation of a function is y = 5x+ . Find the value of y
i)
when x = -3
ii)
when x =1
2​

Answer 1

Answer:

Subtract

2

from both sides:

0

−

2

=

−

5

x

+

2

−

2

−

2

=

−

5

x

Divide both sides by

−

5

:

−

2

−

5

=

−

5

x

−

5

2

5

=

x

x

=

2

5

The

x

-intercept is at

(

2

5

,

0

)

.

To find the

y

-intercept, plug in

0

for

x

and solve for

y

:

y

=

−

5

(

0

)

+

2

y

=

0

+

2

y

=

2

The

y

-intercept is at

(

0

,

2

)

.
