Question

Which equation matches the graph?

Answer 1

A. y = 3x – 8
B. y = –2x + 1
C. y = –4x – 1
D. y = 2x – 5

Answer 2

The equations are in the formula: `y = mx + b`

where
m = slope
b = y-intercept

To start off, the easiest thing to locate here is the y intercept (where the line crosses the y-axis)

where would that be?

Answer 3

C

Answer 4

or

negatives

Answer 5

Yes, C would be the appropriate answer here.

A and D could be eliminated because the line is going downwards meaning it has a negative slope.

B can be eliminated because the y-intercept is at -1 NOT +1.

Which leaves us with C, meaning `y = –4x – 1` is the equation for this line.
