Question

Please help me with this math problem

Answer 1

Answer:

see below

Step-by-step explanation:

5x - 6y = 21

Let x = 0 and solve for y to find the y intercept

-6y = 21

Divide by -6

y = 21/-6 = -7/2

The y intercept is (0,-7/2)

5x - 6y = 21

Let y = 0 and solve for x to find the x intercept

5x = 21

Divide by 5

y = 21/5 = 21/5

The x intercept is (21/5,0)

Answer 2

Answer:

x=4.2 (x-intercept)

y=-3.5 (y-intercept)

Step-by-step explanation:

To find the x-intercept, we know that y=0. To find the y-intercept, we know that x=0. All we have to do is plug in 0 into either x or y to find the x-intercept and y-intercept.

X-intercept

5x-6(0)=21

5x-0=21

5x=21

x=4.2

Y-intercept

5(0)-6y=21

0-6y=21

-6y=21

y=-3.5
