OpenStudy (mathstudent55):

The slope-intercept form of the equation of a line is \(y = mx + b\) where m = slope, and b = y-intercept.

OpenStudy (mathstudent55):

Using the above information, you should be able to answer the questions.

D?

OpenStudy (agent0smith):

D has a y-int. of 3. Use the given points to work out what the slope it.

OpenStudy (agent0smith):

Use the slope formula, you've seen it before.

OpenStudy (mathmale):

Please show your work; that way others can give you more pointed and helpful info. Given y = -2x + 3, we should see immediately that the slope is -2 and the y-intercept is +3. Again, match up this info with one of the four given graphs.
