Question

Find the x-intercept and

the y-intercept from the
following linear equation:
4x + 7y = 28
X-intercept ([?], [ 1)
y-intercept ([ 1, 1)

Answer 1

X-intercept: (7, 0)

Y-intercept: (0, 4)

Explanation:

X-intercept means y-coordinate of 0:

4x +7×0 = 28

4x = 28

x = 7 ← x-coordinate

Y-intercept means x-coordinate of 0:

4×0 +7y = 28

7y = 28

y = 4 ← y-coordinate
