slopeRate of change
y intercept
Write an equation of a line in slope intercept form with a slope of -3 and a
y intercept of 4 y = mx + b
slope y intercept-3 4
y = x + -3 4
Write an equation of a line in slope intercept form with a slope of ½ and a y
intercept of -7
y = mx + b
slope y intercept½ -7
y = x + ½ -7 y = ½ x - 7
