Different Forms Linear Equations

For the equation
y + 1 = -3(x - 5),
the line contains the point (5, -1) and has a slope of?

• -1

• 1

• -3

• 5

What form is this in?

• Standard Form

• Point Slope Form

• Slope Intercept

• Direct Variation Form

Answer explanation

When looking at this form, we can identify our slope (m) and our y-intercept (b) so it is our Slope-Intercept Form.

What form is this in?

• Standard Form

• Point Slope Form

• Slope Intercept

• Direct Variation

Answer explanation

When looking at this form, we can identify our slope (m) and a point (x1,y1) so it is our Point-Slope.

What form is this in?

• Standard Form

• Point Slope Form

• Slope Intercept

• Direct Variation

What is the y-intercept in the equation y= -2x + 5

• -2

• 3

• 5

• Cannot be Determined

Answer explanation

In slope intercept form (y=mx+b) remember the value in place of b is our y-intercept.

For the equation
y - 3 = 2(x + 4),
the line has a slope of 2 and contains what point?

Name the x- and y-intercepts for the equation:
2x + y = 6

Find the x and y intercepts of 4x - 5y = 40

Which equation is written in STANDARD form?

• y = 1/2x + 2

• y - 3 = -5(x + 2)

• 7x + 2y = 9

• 3x + 2 = y

Put this into standard form:

y = 3x + 2

• y + 3x = 2

• 3x + y = 2

• 3x - y = -2

• 3x - 2y = 2
