Answer

The given equation has a slope of $15.6$ and a y-intercept of $292$.

Work Step by Step

RECALL: The slope-intercept form of a linear equation is y=mx+b where m=slope and b=y-intercept. $\\\\$Write the given equation in slope-intercept form (by isolating the variable y) to have: $\\\\78x-5y=-1460 \\\\-5y=-78x-1460 \\\\\dfrac{-5y}{]-5}=\dfrac{-78x-1460}{-5} \\\\y=15.6x+292$ $\\\\$This equation has a slope of 15.6 and a y-intercept of 292.
