The question is slope-2, passes through (0, -9)
The equation of a line with slope m and passing through point (x[sub:1ha8yc4d]1[/sub:1ha8yc4d], y[sub:1ha8yc4d]1[/sub:1ha8yc4d]) will be:
y - y[sub:1ha8yc4d]1[/sub:1ha8yc4d] = m * (x - x[sub:1ha8yc4d]1[/sub:1ha8yc4d])
My answer is -2=0(-5)+b
-2-0=b
-2=b
y=-2x-2 <<<< This line does not pass through (0,-9)
is this correct?
And can someone show me how do this one
passes through(-2,-4) and (1,
The equation of a line passing through points (x[sub:1ha8yc4d]1[/sub:1ha8yc4d], y[sub:1ha8yc4d]1[/sub:1ha8yc4d]) and (x[sub:1ha8yc4d]2[/sub:1ha8yc4d], y[sub:1ha8yc4d]2[/sub:1ha8yc4d])will be:
[y - y[sub:1ha8yc4d]1[/sub:1ha8yc4d]]/[y[sub:1ha8yc4d]2[/sub:1ha8yc4d] - y[sub:1ha8yc4d]1[/sub:1ha8yc4d])] = [(x - x[sub:1ha8yc4d]1[/sub:1ha8yc4d])]/[(x[sub:1ha8yc4d]2[/sub:1ha8yc4d] - x[sub:1ha8yc4d]1[/sub:1ha8yc4d])]
