Slope = –1, y-intercept = 6

y=mx+c

where m is the slope/gradient and c is the y-intercept,

so with the values given we get the equation

y= -1x+6

to find the x intercept y=0

0= -1*x+6

-6=-1*x

-6/-1 = x

6=x

and to confirm the y-intercept... x=0

y= -1*0+6

y= 6

Step-by-step explanation:

Use the point-slope formula the equation of the line is :

y - y_1 = m(x - x_1)

in this exercice :  m = -1        x_1 = 0       y_1 = 6

so :  y - 6 = -1(x - 0)  

y = -x +6

y=mx+

part a

in a city ice cream is mostly only bought when the temperature is very high as ice cream cools down our

so we can derive the conclusion that as the temperature increases the number of ice creams sold also increases

part b

y intercept is 5

slope is 2
