The slope of a line is 2. The y-intercept of the line is –6. Which statements accurately describe how to graph the function? Locate the ordered pair (0, –6). From that point on the graph, move up 2, right 1 to locate the next ordered pair on the line. Draw a line through the two points. Locate the ordered pair (0, –6). From that point on the graph, move up 2, left 1 to locate the next ordered pair on the line. Draw a line through the two points. Locate the ordered pair (–6, 0). From that point on the graph, move up 2, right 1 to locate the next ordered pair on the line. Draw a line through the two points. Locate the ordered pair (–6, 0). From that point on the graph, move up 2, left 1 to locate the next ordered pair on the line. Draw a line through the two points.

The y-intercept is the y value when x = 0 --> (0, y) or the point where the line crosses through the y-axis.

The slope(m) is:

"rise" is the number of units you go up(+) or down(-) from each point

"run" is the number of units you go to the right from each point

You know:

y-intercept = -6 or (0, -6)

m = 2 or , so from each point you go up 2 units and to the right 1 unit to get to the next point.

#1: Locate the ordered pair (0, –6). From that point on the graph, move up 2, right 1 to locate the next ordered pair on the line. Draw a line through the two points.

This is true

#2: Locate the ordered pair (0, –6). From that point on the graph, move up 2, left 1 to locate the next ordered pair on the line. Draw a line through the two points.

This isn't accurate because the slope doesn't move left.

#3: Locate the ordered pair (–6, 0). From that point on the graph, move up 2, right 1 to locate the next ordered pair on the line. Draw a line through the two points.

This isn't accurate because (-6, 0) isn't the y-intercept or a point on the y-axis

#4: Locate the ordered pair (–6, 0). From that point on the graph, move up 2, left 1 to locate the next ordered pair on the line. Draw a line through the two points.

This isn't accurate because (-6, 0) isn't the y-intercept or a point on the y-axis, and the slope doesn't move to the left.

Responder:

x = 15/7

Explicação passo a passo:

Dada a equação:

7 x + 4 = 19

Subtraia 4 de ambos os lados

7x + 4 - 4 = 19 - 4

7x = 15

Divida os dois lados por 7

7x / 7 = 15/7

x = 15/7
