Me on one or two i don’t really understand?

Step-by-step explanation:

I'm assuming that you need to graph these equations.

m, or the slope, is the fraction that is next to x.

For example.

If the slope is like on problem 7,

The function would rise 2 and run 1.

b, or the y-intercept, tells you where the equation crosses the y-axis.

Again, on problem #7, b = -2. That means that when x=0, y=-2 or the point (0,-2)

To graph this equation. Begin by placing a point at (0,b). Then the next point will be the rise and run of the equation. Then you can draw a straight line between these two points.

Slope-intercept form: y = mx + b   (m is the slope, b is the y-intercept, or the y value when x = 0 ---> (0, y)]

For #1:

y = mx + b

b = -2

#2:

y = mx + b

b = -4

To graph this line, you can start at the y-intercept, then use the slope to find the next point, and then you can draw a line from the y-intercept to the point you just found.

For example in #1:

Your y-intercept is -2 or (0, -2), so you can start making a point there. Now you use the slope, which is -2/5. From (0, -2), you go down 2 units, then to the right 5 units, and that point you found should be (5, -4)

The slope tells you how many units you need to go up (+) or down (-) and to the right.

When the slope is positive, (ex: 3), you go up (3 units) and to the right 1 unit

When the slope is negative, you go down 3 units, and to the right 1 unit.  The denominator tells you how many units you move to the right.

“a term can be a signed number, a variable, or a constant multiplied by a + sign or j sign. in , the terms are 5x , 3y and 8. when a term is made up of a constant multiplied by a variable or variables, that constant is called a coefficient.” i hope this you.
