y-intercept (0, -7) and x-intercept (5,0)

1) To find the y-intercept, let's rewrite that equation into the slope-intercept form to better do it:

2/5x -2/7y =2 Add 2/7y to both sides

-2/7y = 2 -2/5x Multiply the whole equation by 7 to get rid of the fraction x

-2y = 14 -14/7x Divide by -2

y = -7 +x

y= x -7

So the y-intercept is at y=-7

2) To find the x-intercept, let's plug into that y=0

2/5x -2/7y =2

2/5x -2/7(0) = 2

2/5x = 2

x= 2 : 2/5

x = 2 x 5/2

x= 5

3) Hence, the answer is y-intercept (0, -7) and x-intercept (5,0)
