What does a linear graph look like

Question 1

What does the graph of linear function look like?

y = mx + c

Answer 1

It is a straight line

Question 2

What does m in the linear function represent

y = mx + c

Answer 2

It represents the gradient

It measures the slope of the line

Question 3

When m is positive, what does the line look like

y = mx + c

Answer 3

The gradient is positive and slopes upwards from left to right

Question 4

When m is negative, what does the line look like

y = mx + c

Answer 4

The gradient is negative and slopes downwards from left to right

Question 5

What does c in the linear function represent

y = mx + c

Answer 5

It represents the y intercept

It is where the line intercepts the y-axis

Question 6

When c is positive, what does the line look like

y = mx + c

Answer 6

The line intercepts the y -axis above the x-axis

Question 7

When c is negative, what does the line look like

y = mx + c

Answer 7

The line intercepts the y -axis below the x-axis

Question 8

Which linear function is this

y = 9x + 9

y = 9x -9

y = -9x + 9

y = -9x - 9

Answer 8

y = -9x - 9

Question 9

Which linear function is this

y = 9x + 9

y = 9x -9

y = -9x + 9

y = -9x - 9

Answer 9

y = 9x - 9

Question 10

Which linear function is this

y = 9x + 9

y = 9x -9

y = -9x + 9

y = -9x - 9

Answer 10

y = 9x + 9

Question 11

Which linear function is this

y = 9x + 9

y = 9x -9

y = -9x + 9

y = -9x - 9

Answer 11

y = -9x + 9
