Question

(a) Write the equation in slope-intercept form.

y = −(x − 5)

(b) Write the equation in slope-intercept form.

y + 2x = 6

A restaurant serves 80 customers per hour.

(a) Write an equation that relates the number of customers C and time t.

Use the slope and y-intercept to sketch the graph of each equation.

(a)    

y = 3x + 2

Identify the x-intercept.

b)    

y = − 1/5x

Identify the x-intercept.

(c)    

y = 3/2x-6

Identify the x-intercept.

(d) y = −5x + 8

Identify the x-intercept.

Answer 1

SOLUTION:

a) the equation y=-(x-5)

the slope intercept form is y=mx+b

the slope intercept form is y=-x+5  

b)  the equation y+2x=6

the slope intercept form is y=-2x+6

a)  rite an equation that relates the number of customers C and time t.

is C= 80t

where t=time in hour C= customer surved

PART-C

a) y=3x+2

x-intercept=(-2/3,0)

b)  

x-intercepts (0,0)

c)  

x-intercepts (4,0)

.

d) y=-5x+8

x-intercepts is
