Question

The value of the function at 0 is 4 find the y-intercept if the slope is 4

The value of the function at 0 is -3 find the x-intercept if the slope is 7

The value of the function at 0 is 2 find the x-intercept if the slope is -2

Answer 1

f(0)=4 we write the equetion in the form of

`f(x) = mx + b`

which is

• f(x) = y = function at x
• m= slop
• b= y-intercept

1st f(x)= 4x+4 then y-intercept is b= 4

2nd f(x) = 7x-3 then x-intercept is x=3/7

3rd f(x)= -2x + 2 then x-intercept is x= 1
