Question

If somebody's good at slope intercept forms i'd love your help on these questions

Answer 1

• y=-1/4x+7

Slope=-1/4

#1

Perpendicular lines hAve slopes negative reciprocal to each other

• Slope of perpendicular line=4

So

equation is

• y=4x+c

c is y intercept

• Option B

#2

Parallel lines have equal slopes

• slope=-1/4

Option D

Answer 2

1) b 2)d

Explanation:

To find an equation that is perpendicular to a certain equation, find the reciprocal of the slope and switch the sign. For parallel, find an equation with the same slope and the same sign. Disregard the y-intercept if you're just trying to find the perpendicular or parallel equation
