Answer:
y=-3x+4
Explanation:
the equation for a line: y=mx+b
m stands for slope
b stands for the y-intercept
the slope is -3 because
1. the line is negative so it has a negative sign
2. from points (1,1) and (0,4) you go up 3 and over 1
m/slope= rise over run or rise/run
the y-intercept is 4 because
1. when the line reaches 0 on the x-axis that's where you find the intercept
2. you can use the graph and go to y-axis line and see that is goes through the point (0,4)
Hope this helps :D
