Find the slope-intercept form for the line satisfying the conditions.
How do I solve this. Parallel to y = -2x passing through (7,8)
**
Standard form of equation for a straight line: y=mx+b, m=slope, b=y-intercept
For given problem:
slope m=-2 since line is parallel to y=-2x whose slope=-2.
equation: y=-2x+b
solve for b using (x,y) coordinates of given point (7,8)
8=-2*7+b
b=8+14=22
equation: y=-2x+22
