For each line described, write an equation in(a)slope-intercept form, if possible, and(b)standard form. through (-7, 4), perpendicular to y=8

The slope-intercept form of a linear equation is expressed as y = mx + b, where m represents the slope of the line and b is the y-intercept. This form is useful for quickly identifying the slope and y-intercept, making it easier to graph the line. To convert an equation into this form, one typically isolates y on one side of the equation.

The standard form of a linear equation is given by Ax + By = C, where A, B, and C are integers, and A should be non-negative. This form is particularly useful for analyzing the relationship between x and y and for solving systems of equations. To convert from slope-intercept form to standard form, one rearranges the equation to fit this structure.

Two lines are perpendicular if the product of their slopes is -1. This means that if one line has a slope of m, the slope of the line perpendicular to it will be -1/m. In the context of the given question, since the line y = 8 is horizontal (slope = 0), the perpendicular line will be vertical, which cannot be expressed in slope-intercept form but can be represented in standard form.
