Pierce used the proportion y/x=7/2 when deriving the equation of a line with similar triangles.select 2 that apply and explain

a.the slope of line is 0
b.the slope of line is 2/7
c.the slope of line is 7/2
d. the y int is 0
e.the y int is 2/7 f the y int is 7/2 and again explain plz

Respuesta :

[tex] \frac{y}{x} = \frac{7}{2} [/tex]
Cross multiply.

2y = 7x
Solve for y.

y = 7/2x


C) The slope of the line is 7/2
D) The y-intercept is 0

You know the slope is 7/2 because it is the coefficient of x.
You know the y-intercept is 0 because there is no other number besides 7/2x, which is the slope.
