Question

Identify the equation in slope-intercept form for the line containing the point (0,7) and perpendicular to y=−5/4x+11/4. HELP PLEASE!!

Answer 1

To write the equation of a line I need slope and y intercept (0,y)

I have y intercept (0,7)  of +7 as written in the equation

The equation y=-5/4x + 11/4 has a slope of -5/4

To get perpendicular slope is negated reciprocal

so take -5/4 and flip it -4/5 and change the sign (in this case negative to positive)  4/5

so the new equation is y=4/5x +7 (third one)
