Answer:line b
Explanation:
In general, the slope intercept form assumes the formula: y = mx + b.
M is the slope (lesson on slope)
Mnemonic : 'm' means 'move'
B is the y-intercept (lesson on the y-intercept)
Mnemonic: 'b' means where the line begins.
B is where it intercepts so 1 intercepts the y axis and the only line that intercepts the y axis at 1 is line b
