What is the value of x? x=32 x=36 x=37 x=40

x = 40

Step-by-step explanation:

Always when you have a line and another line that cuts it, two consecutive angles always add up to 180° (the plane angle)

Then, in this case we can see that:

x + (4*x - 20) = 180

for the internal angle of the right and the external one.

now, we can solve this equation for x.

x + 4*x - 20 = 180

5*x = 180 + 20 = 200

x = 200/5 = 40

step-by-step explanation:

let

we know that

the y-intercept is the y-coordinate of the point when the value of x is equal to zero

so

the y-coordinate of the point a is the y-intercept

the answer part a) is

the value of y-intercept is

part b) find the slope m

we know that

the value of the slope is equal to

substitute the values

therefore

the answer part b) is

the value of the slope is equal to

the general answer is

the slope is

the value of y-intercept is

a
