The point-slope form makes use of the slope and a point on the line. The point-slope form is given by the formula: $y - y_1 = m(x - x_1)$, where $m$ is the slope and $(x_1, y_1)$ is a point on the line. The slope-intercept form contains both the slope and the y-intercept and is given by the formula: $y = mx + b$, where $m$ is the slope and $b$ is the y-intercept. The standard form is given by the formula: $Ax + By = C$ a. This equation is in point-slope form, where the slope is $-1$ and the point is $(2, -5)$. b. This equation is in point-intercept form, where the slope is $-2$ and the y-intercept is $5$. c. This equation is in point-slope form, where the slope is $-2$ and the point is $(1, 10)$. d. This equation is in standard form.
