Question

Determine the slope and y-intercept of the graph:
2x + 5y = 10

A_m = 2⁄5, b = -2

B_m = -2⁄5, b = -2

C_m = -2⁄5, b = 2

D_m = 2⁄5, b = 2

Answer 1

C is the correct answer,

y=(-2/5)x+10/5

Answer 2

Slope = - a/b = - 2 /5

So, m = - 2/5

For y- intercept,

Divide the whole equation by 10., to get the equation in the form of x/a + y/b = 1.

2x/10 + 5y/10 = 10/10

x/5 + y/2 = 1

So, y - intercept is 2. y - intercept means value of b.

So, Correct option is C). m = - 2/5, b = 2.
