If you know that a line has a slope of 2/3 and a y-intercept of 7, what is the equation for that line in slope-intercept form?

Mathematics

the equation for a line is y = mx+b

 m = slope

b = y intercept

 you know the slope is 2/3 and the y intercept is 7 so just replace them in the equation:

 y =2/3x +7

Simple...

you have: 

1.) Find the slope of the line using (-2,1) and (3,6)

Using \frac{ y_{1}-  y_{2} }{ x_{1} - x_{2}  }

\frac{1-6}{-2-3} = \frac{-5}{-5}

m=1 (slope)

2.)Tell whether the equation, 8y+3=5x+3, is a direct variation.

y=\frac{5x}{8} (None)

3.)What is the slope and y-intercept of the graph of the equation y=2x+3?

Slope =2 

y-intercept=3

C.

Thus, your answer.
