Coordinates of the y-intercept is (0, -5)

Step-by-step explanation:

Step 1: Given the slope of the line, m = 3. Point on the line is (1, -2). Here x = 1 and y = -2. Substitute in the equation y = mx + b to find b.

⇒ -2 = 3 × 1 + b

⇒ b = -5

⇒ Coordinates = (0, -5)

BRAINLEST IF CORRECT!!!!which of the d-values satisfy the following inequality? d/5>4

irinina [24]

Answer:

d = 25

Step-by-step explanation:

$\frac{d}{5} >4$

The value of d has to satisfy the inequality

so replace d with one of the given options

$\frac{25}{5} >4$

We have to simplify the fraction first

$\frac{25}{5} =5>4$

Create an equation with the indicated number of solutions.

GenaCL600 [577]

An equation that doesn't have a solution would have to end up as something impossible when you solve it all out, like
5=3.

When you simplify your equation out, you get

3x-4=3x+?

Subtract 3x from both sides.

-4=?

From this, you can tell that you need to out something in the ? that will make the equation false, or something that doesn't equal -4.

You could put anything in the ? as long as it is not -4.

Hope this helps!
