Answer:

The correct option is B) x = negative three fifths y + 3

Step-by-step explanation:

Consider the provided equation.

5x + 3y = 15

We need to solve the above equation for x.

Subtract both the side by 3y.

5x + 3y-3y = 15-3y

5x= 15-3y

To find the value of y, isolate the variable y:

Divide both the sides by 5.

\frac{5x}{5}= \frac{15}{5}-\frac{3y}{5}

x= 3-\frac{3y}{5}

x= -\frac{3y}{5}+3

Hence, the correct option is B) x = negative three fifths y + 3

Danielle plans to graph the linear equation 5x-2y=10 by plotting the x-intercept and y-intercept.
lesya692 [45]

x-intercept is (2,0)

y-intercept is (0,-5)

Step-by-step explanation:

Danielle plans to graph the linear equation 5x-2y=10 by plotting the x-intercept and y-intercept.

Finding x-intercept

X-intercept: Substitute 0 for y and then solve for x. Write your answer in the form (__, 0)

Putting y=0

5x-2y=10\\5x-2(0)=10\\5x=10\\x=10/5\\x=2

So, x-intercept is (2,0)

Finding y-intercept

Y-intercept: Substitute 0 for x and then solve for y. Write your answer in the form (0, __)

Putting x=0

5x-2y=10\\5(0)-2y=10\\-2y=10\\y=10/-2\\y=-5

So, y-intercept is (0,-5)
