You can put this solution on YOUR website! Equation for a line: y=mx+b
m=slope
b=y intercept
2. a) m=4 point (0,2)
y=4x+b
substitute (0,2) into the equation y=mx+b
0=x
2=y
2=4(0)+b
2=0+b
2=b
Therefore, y=4x+2
2.b) m=-5 point (3,4)
y=-5x+b
4=-5(3)+b
4=-15+b
4+15=b
19=b
Therefore, the equation of the line is y=-5x+19
2.c) m=0 point (1,2)
2=0(1)+b
2=0+b
2=b
Therefore, y=2
