Which of these can be the graph of the equation y=mx+b
Lostsunrise [7]

See the explanation

<h2>Explanation:</h2><h2></h2>

Hello! Your figures are missing, so I could help you in a general way. The Slope-intercept form of the equation of a line is given by the form:

y=mx+b \\ \\ \\ m:Slope \\ \\ b=y-intercept

Case 1:

m>0

If the slope is positive, we will have a line as the form illustrated in figure 1. So as x increases y also increases.

Case 2:

m

If the slope is negative, we will have a line as the form illustrated in figure 2. So as x increases y decreases.

Case 3:

m=0

If the slope is zero, we will have a line as the form illustrated in figure 3. here we have a constant function.

Case 4:

m: undefined

If the slope is undefined, we will have a line as the form illustrated in figure 4.

Roberto wrote a sentence that describes an equation.
tresset_1 [31]
The last one: x/2=45; x = 90
the problem says: half of a number is 45.

let's use x to represent this number
we know that dividing by 2 halves a number, so, x/2 = 45

to get x alone, we multiply 2 by 2 to cancel it out. so, multiply by 2 on both sides

x/2 • 2 = 45 • 2

x = 90

hope this helped!
