x+y= 5

change this so it becomesy = 5 -x

This way, u can choose any x value and subtitute it in to get y.

ie. x = 0

y = 5 - 0

y = 5

Point (0, 5)

Choose at least 3 other points to draw the line.

x-y=1

Do the same.

y = x -1

Choose at least 3 other points to draw the line.

What is the point of intersection of the two lines?

In the graph I made the dots red, where the lines intersects x and y axes.

What is the slope of line y=3/4x-1?

This is in the form of y = mx + c

m is the slope so slope = 3/4

What is the y-intercept of line 2x+3y=6?

Y intercept is when x = 0

Substitute this in and you get: 2*0 + 3y = 6

3y = 6

y = 2

Y-intercept = (0, 2)

Find an equation of the line with slope -4/3 and y-intercept 3. Leave equation in slope-intercept form.

I don't know if this is what they are looking for.

3 = -4/3x + c

Y - Int. x = 0

y = -4/3 + 3

Find an equation of the line that goes thru the point (2,1) and has a slope of 4. Leave equation in point-slope form.

I don't know if this is what they are looking for.

1 = 4x + c

1 = 8 + c

c = -7
