Master Writing the equation of a line through a point given the slope

The video tutorial explains how to write equations in slope intercept form when given a point and a slope. It covers two methods: using slope intercept form directly and using point slope form. The tutorial provides examples to illustrate each method, emphasizing the importance of identifying the Y-intercept and using given points effectively. The video concludes with a demonstration of point slope form, highlighting its usefulness when a point and slope are provided.

What is the slope-intercept form of a linear equation?

• X = MY + B

• Y = B + MX

• X = BY + M

• Y = MX + B

In the equation Y = MX + B, what does 'M' represent?

• The slope

• The origin

• The y-intercept

• The x-intercept

If a point has an x-coordinate of 0, what does this point represent on the graph?

• The y-intercept

• The x-intercept

• The origin

• The slope

How do you find the y-intercept when given a point and a slope?

• Plug the point into the equation and solve for B

• Multiply the slope by the x-coordinate

• Subtract the x-coordinate from the y-coordinate

• Divide the y-coordinate by the slope

What is the first step in using the slope-intercept form with fractions?

• Rewrite the equation as Y = MX + B

• Add the fractions together

• Multiply the slope by the x-coordinate

• Convert all fractions to decimals

What is the point-slope form of a linear equation?

• X - X1 = M(Y - Y1)

• Y - Y1 = M(X - X1)

• Y = MX + B

• Y = B + MX

When is it most useful to use the point-slope form?

• When you have two points

• When you have a point and a slope

• When you have the y-intercept

• When you have the x-intercept
