Question 502090: Write an equation in slope-intercept form for the line that satisfies each set of conditions.
x-intercept -5, y-intercept 7

You can put this solution on YOUR website!
y-intercept = 7: (0,7)
x-intercept = -5: (-5,0)
So you can draw the line
.
y = mx + b
b = 7
.
What is 'm'?
.
m = change in y / change in x
.
change in y = (0-7) = -7
change in x = (-5-0) = -5
m = 7/5
.
y = 7/5x +7
.
