Write an equation of the line in slope-intercept form that crosses the y-axis at 3 and increases at a rate of 1?

y = x - 3
y = x + 3
y = -x + 3
y = 3x + 1

increases at a rate of 1....so ur slope is 1
crosses the y axis at 3...so ur y intercept is 3

in slope intercept form, y = mx + b, the slope will be in the m position and the y intercept will be in the b position

y = mx + b
slope(m) = 1
y int (b) = 3
sub
y = 1x + 3...which can be written as y = x + 3 <=
