Question

Y=-2x-21 determine the intercepts of the line (,) (,) ASAPPPP

Answer 1

x intercept (10.5,0)

y intercept (0, -21)

Explanation:

y=-2x-21

there are two intercept for a line

x intercept, the point of given equation of line which lies on x axis.

For x intercept corodinate of y is o

Thus, value x intercept is form (x,0)

putting these value in y=-2x-21, we find x intercept

0=-2x-21

2x = 21

x = 21/2 = 10.5

Thus, x intercept (10.5,0)

Y intercept, the point of given equation of line which lies on y axis.

For Y intercept coordinate of x is o

Thus, value y intercept is form (0,y)

putting these value in y=-2x-21, we find y intercept

y = -2*0 -21

y = -21

Thus, y intercept (0, -21)
