Find the x-intercept of the graph of y = a x + b. (Assume b ≠ 0.)

-b/a =x

Step-by-step explanation:

To find the x intercept, let y =0 and solve for x

0 =ax+b

Subtract b from each side

-b = ax+b-b

-b = ax

Divide each side by a

-b/a = ax/a

-b/a =x

x intercept=-b/a

y intercept=b

Step-by-step explanation:

to find x intercept put y=0

0=ax+b

ax=-b

x=-b/a

to find y intercept put x=0

y=b

for this case we have by definition, if two lines are perpendicular, then the product of their slopes is -1.

then, given the following line:

so,

we are looking for m_ {2}:

then, the line is given by:

we find "b" replacing the given point:

finally, the equation is:

option c

the answer is c: divide the arc's degree measure by 360°, then multiply by the circumference of the circle.
