Slope

What is the purpose of using slope-intercept form in linear equations?

• To find the slope of the line

• To find the y-intercept

• To graph the line

• To model real-world situations

What formula is used to graph linear equations in slope-intercept form?

• y = mx + b

• y = ax^2 + bx + c

• y = mx + c

• y = ax + b

Write the equation of the line.

• y= -1x-3

• y= -3x-1

• y=-1/3x-1

• y= -3x-3

What is the y-intercept of this graph?

• (0,1)

• (0,-2)

• (0,0)

• (0,3)

The y-intercept is where the line crosses . . .

• the x-axis.

• the origin and only the origin.

• the y-axis.

• k.

What is the equation of a line with a slope of 4 and a y-intercept of 2?

• y = -4x + 2
