For the linear equation

y = 20 - 17 x

, explain what the

y

-intercept and slope represent in terms of the graph of the equation.
A)The

y

-intercept,

b _ { 0 } = 20

, gives the

y

-value at which the straight line

y = 20 - 17 x

intersects the

y

-axis. The slope,

b _ { 1 } = 17

, indicates that the

y

-value increases by 17 units for every increase in

x

of 1 unit.
B) The

y

-intercept,

b _ { 0 } = 20

, gives the

y

-value at which the straight line

y = 20 - 17 x

intersects the

y

-axis. The slope,

b _ { 1 } = - 17

, indicates that the

x

-value decreases by 17 units for every increase in

y

of 1 unit.
C) The

y

-intercept,

b _ { 0 } = - 17

, gives the

y

-value at which the straight line

y = 20 - 17 x

intersects the

y

-axis. The slope,

b _ { 1 } = 20

, indicates that the

y

-value increases by 20 units for every increase in

x

of 1 unit.
D) The

y

-intercept,

b _ { 0 } = 20

, gives the

y

-value at which the straight line

y = 20 - 17 x

intersects the

y

-axis. The slope,

b _ { 1 } = - 17

, indicates that the

y

-value decreases by 17 units for every increase in

x

of 1 unit.
